Display Device, Corresponding Systems, and Methods Therefor

ABSTRACT

A display system includes a display and a control circuit operable with the display. The display is configured to provide visual output having a presentation orientation. When user input is received, the control circuit can alter the presentation orientation from an initial orientation in response to user input. When non-user events or device events are detected, the control circuit can revert the presentation orientation to the initial orientation in response to the non-user event or device event. Where the presentation orientation has a user input configuration associated therewith, the user input configuration can either be altered with the presentation orientation or retained in an initial disposition.

BACKGROUND

1. Technical Field

This invention relates generally to user interfaces, and moreparticularly to devices, methods, and systems for orienting informationon user interfaces and displays.

2. Background Art

Electronic devices, such as mobile telephones, smart phones, gamingdevices, and the like, present information to users on a display. Asthese devices have become more sophisticated, so too have their displaysand the information that can be presented on them. For example, not toolong ago a mobile phone included a rudimentary light emitting diodedisplay capable of only presenting numbers and letters configured asseven-segment characters. Today, high resolution liquid crystal andother displays included with mobile communication devices and smartphones can be capable of presenting high resolution video.

The display output is generally oriented so as to be aligned with thedevice. Said differently, many electronic devices have an identifiabletop and bottom. Display output is aligned in a complementary manner,with the top of the display output appearing towards the identifiabletop of the device, and the bottom of the display output being alignedwith the bottom of the device.

Some devices allow the display output to be rotated. For example, somedevices have a gravity detector that is configured to rotate the outputbased on a detected gravitational field. Thus, as the device is rotated,the “top” of the output always stays above the bottom of the output.

While rotating display output based on gravity can be useful, it failsto provide suitable display output alignment in all situations. It wouldbe advantageous to have an improved display device with improved displayorientation capabilities.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Before describing in detail embodiments that are in accordance with thepresent invention, it should be observed that the embodiments resideprimarily in combinations of method steps and apparatus componentsrelated to altering a presentation orientation of visual indicia on adisplay in response to user input and then reverting the presentationorientation to an initial orientation in response to a device event,which can be a non-user initiated event. Any process descriptions orblocks in flow charts should be understood as representing modules,segments, or portions of code that include one or more executableinstructions for implementing specific logical functions or steps in theprocess. Alternate implementations are included, and it will be clearthat functions may be executed out of order from that shown ordiscussed, including substantially concurrently or in reverse order,depending on the functionality involved. Accordingly, the apparatuscomponents and method steps have been represented where appropriate byconventional symbols in the drawings, showing only those specificdetails that are pertinent to understanding the embodiments of thepresent invention so as not to obscure the disclosure with details thatwill be readily apparent to those of ordinary skill in the art havingthe benefit of the description herein.

It will be appreciated that embodiments of the invention describedherein may be comprised of one or more conventional processors andunique stored program instructions that control the one or moreprocessors to implement, in conjunction with certain non-processorcircuits, some, most, or all of the functions of altering and revertingpresentation orientations of data presented on a display as describedherein. The non-processor circuits may include, but are not limited to,a radio receiver, a radio transmitter, signal drivers, clock circuits,power source circuits, and user input devices. As such, these functionsmay be interpreted as steps of a method to perform presentationorientation alteration and reversion. Alternatively, some or allfunctions could be implemented by a state machine that has no storedprogram instructions, or in one or more application specific integratedcircuits (ASICs), in which each function or some combinations of certainof the functions are implemented as custom logic. Of course, acombination of the two approaches could be used. Thus, methods and meansfor these functions have been described herein. Further, it is expectedthat one of ordinary skill, notwithstanding possibly significant effortand many design choices motivated by, for example, available time,current technology, and economic considerations, when guided by theconcepts and principles disclosed herein will be readily capable ofgenerating such software instructions and programs and ICs with minimalexperimentation.

Embodiments of the invention are now described in detail. Referring tothe drawings, like numbers indicate like parts throughout the views. Asused in the description herein and throughout the claims, the followingterms take the meanings explicitly associated herein, unless the contextclearly dictates otherwise: the meaning of “a,” “an,” and “the” includesplural reference, the meaning of “in” includes “in” and “on.” Relationalterms such as first and second, top and bottom, and the like may be usedsolely to distinguish one entity or action from another entity or actionwithout necessarily requiring or implying any actual such relationshipor order between such entities or actions. Also, reference designatorsshown herein in parenthesis indicate components shown in a figure otherthan the one in discussion. For example, talking about a device (10)while discussing figure A would refer to an element, 10, shown in figureother than figure A.

From an electrical perspective, embodiments described below provide adisplay system, suitable for integration into an electronic device,configured to alter a presentation orientation of visual output. Oneexplanatory electronic device used in the figures is a wearable deviceconfigured as a wristwatch. However, it will be clear to those ofordinary skill in the art having the benefit of this disclosure that thedisplay systems, control circuits, and associated modules used to alterthe presentation orientation could be integrated into any of a number ofportable electronic devices, including mobile telephones, personaldigital assistants, smart phones, palmtop computers, tablet devices,portable computers, and so forth.

The display is configured to present visual output having a presentationorientation. The presentation orientation refers to how the visualoutput is oriented relative to either the earth or the electronic deviceitself. For example, when the electronic device is held vertically withits top above its bottom, a presentation orientation with reference tothe earth can be more useful and appropriate. If the visual output ispresented with the top of the content being nearer the top of thedevice, the presentation orientation can be considered to be “right sideup.” Similarly, of the visual output is presented with the top of thecontent below the bottom of the content, the presentation orientationcan be considered to be “upside down.” These references can be withoutreference to the device itself. In this example the reference to theearth can be determined by using sensors that detect acceleration due tothe earth's gravity such as accelerometers, or with gyroscopes thatdetect a change in motion of the device.

However, when the electronic device is held horizontally, the effect ofgravity on accelerometers in the device remains relatively constant. Inthis case an alternative method would need to be used to detect areorientation of the device. When the top of presented content is nearerthe first side of the device, a first presentation orientation isestablished. When the presented content is altered such that the top ofthe content becomes nearer a second side, a second presentationorientation is established. In this example, the reference to the earthcan be determined with using a sensor that detects the earth's magneticfield such as an electronic compass or changes in position andorientation using methods such as GPS location or gyroscopes. In thisexample, the first presentation orientation can remain constant in spaceeven though the device is translated or rotated.

Alternatively, the presentation orientation can be referenced to theelectronic device. When the top of presented content is nearer the firstside of the device, a first presentation orientation is established.When the presented content is altered such that the top of the contentbecomes nearer a second side, a second presentation orientation isestablished such that the top of the presented content is alwaysdisposed toward the side of the device that is on “top” in the givenorientation. As with the earth-referenced cases, the device can be heldhorizontally or vertically.

When the display initially presents visual output, it has an initialpresentation orientation. A control circuit that is operable with thedisplay can then be configured to alter the presentation orientation inresponse to user input. For example, if the display is a touch sensitivedisplay, the user may swipe a finger or stylus across the display torotate the display to a second presentation orientation. For instance, auser may be holding a tablet-style computer horizontally, with theuser's body located on a first side of the tablet-style computer. Afriend may be standing near the tablet-style computer, with the friend'sbody being positioned on a second side of the tablet-style computeropposite the first side. When the user wants to show a picture beingpresented as visual output from the display to the friend that has a“correct” presentation orientation for the friend, the user may make arotating motion along the display to rotate the picture such that thetop of the picture, initially disposed towards the friend, rotates 180degrees to be nearer the user. In response to this user input, thecontrol circuit alters the presentation orientation from the initialorientation to a second orientation, which is rotated 180 degrees fromthe initial orientation.

In another embodiment, a user may swipe a touch sensitive display in thedirection of their friend by “drawing” a line beginning at user's sideand ending at friend's side. In another embodiment, rotation of contentcan be achieved by tilting device toward the friend while center of thedevice is held stationary in three-dimensional space. This distinguishesthe tilting from random user hand movements, walking, or other motion.As an example, a user can tilt the device toward a friend who isstanding in front of the user. The upper side of the device, nowpointing away from user, can represent the upper side of the rotatedcontent presented to the friend.

In one or more embodiments, the control circuit is then configured torevert the presentation orientation back to the initial orientation inresponse to a non-user event or, alternatively, a user event such as asecond sweep of a finger or stylus across the display. Non-user inputcan refer to input other than intentional display manipulation actionslike the finger sweep described in the preceding paragraph. For example,an incoming email or text message received via wireless communicationwould be one example of non-user input. Similarly, an incoming call isan example of non-user input as well.

In some embodiments, non-user input can include passively detectedconditions pertaining to the user. For example, as will be describedbelow, in one or more embodiments wellness sensors can be disposedwithin an electronic device configured with display alterationcapabilities. These wellness sensors can detect conditions such aspulse, temperature, heartbeat, perspiration, or other conditions. Insuch applications, non-user input can be extended to include sensedwellness conditions such as increased or abnormal heartbeat, increasedor abnormal pulse, or increased perspiration, increased or decreasedtemperature, abnormal blood sugar levels, and the like. When one ofthese conditions is sensed, the control circuit can be configured torevert the presentation orientation back from a user-manipulatedorientation to the initial orientation.

From a mechanical perspective, in one embodiment a detachable module ofthe electronic device includes a first electronic module extensionextending distally from a first side of a housing of the electronicdevice. A second electronic module extension extends distally from asecond side of the housing. In one embodiment, the second side of thehousing is disposed opposite the first side such that the firstelectronic module extension and the second electronic module extensionextend out of opposite sides of the housing, or outward from the housingin directions that are separated radially by 180 degrees.

In one or more embodiments, both the first electronic module extensionand the second electronic module extension are hingedly coupled to thehousing. The hinged connection can be via a simple hinge, a biased hingehaving a pre-loaded force member, a detented hinge, or combinations ofthese. The hinged connection is configured to allow the first electronicmodule extension and the second electronic module extension toselectively pivot to any number of angularly displaced orientationsranging from a closed position, where either the electronic moduleextension is disposed against a major face of the housing, to anangularly displaced open position, where the electronic module extensionis extending distally outward from the housing.

In one or more embodiments, electronic circuitry and components for theelectronic module are disposed exclusively within the housing with asingle exception: an energy storage device, such as a lithium polymerbattery, and accompanying power delivery circuitry (including energystorage device safety and charging circuitry) is disposed within one orboth electronic module extensions. In such a configuration, the energystorage device disposed within the electronic module extension(s) iscoupled through the hinge to the electronic circuitry and componentsdisposed within the housing, and can accordingly supply power to theelectronic components disposed exclusively within the housing. While theelectronic module extensions contain energy storage devices, one or moresmaller energy storage devices can be disposed in the housing as well.

The electronic module extensions can be configured in a variety of formfactors, with each form factor having an aesthetic component, afunctional component, or combinations thereof. For example, in oneembodiment the electronic module extensions can be configured in aplanar configuration so as to form radial extensions from the housing.The electronic module extensions containing the energy storage devicescan be electrically coupled in parallel or series. For the seriesconfiguration, control circuitry can be added to selectively switchenergy storage devices in or out of the circuit based upon stored energystate. In another embodiment, the electronic module extensions can beconfigured with a non-planar geometry, such as an arched shape (whenviewed in cross section). Where energy sources are disposed within theelectronic module extensions, the energy sources can be configured toconform to the form factor of the electronic module extension.Illustrating by example, where the electronic module extension isarched, a lithium polymer cell can be formed as an arch so as to becomplementary to the form factor of the electronic module extension.Such a cell can be constructed on an arched form to result in the archedcell. Alternatively, a planar lithium polymer cell can be arched afterconstruction so as to be complementary to the form factor of theelectronic module extension. Compliant batteries can be used instead toform bendable, compliant electronic module extensions. For instance, auser with small wrist might want to bend the compliantbattery/electronic module extension to provide a better fit.Accordingly, the compliant batteries can be covered with a finish thatdoes not restrict bending. Alternatively, the compliant batteries can behoused inside a flexible housing made from flexible material such asrubber, plastic, or even hard material with embedded features enablingit to bend, such as via hinged links. While some explanatory extensionmodule geometries will be shown herein for illustration, others will bereadily apparent to those of ordinary skill in the art having thebenefit of this disclosure as well. For instance, rather than employingarched cells or batteries, the non-planar geometry can incorporate aseries of segmented cell structures that follow a non-planar extensioncontour.

Functional features can be included into the hinge configuration aswell. For example, in one embodiment the hinge is pre-loaded with abiasing member, such as a spring or elastomer, so as to bias theelectronic module extensions towards the closed position or vice versa.Where configured to bias the electronic module extensions towards theclosed position, the electronic module extensions can be used as “clips”to selectively attach the electronic module to a shirt, backpack, purse,or other article. In another embodiment, the electronic moduleextensions can be configured to couple to a wearer's ear so that thecorresponding electronic module can be used as a hands-free device. Inother embodiments, retention devices—such as magnets—can be disposed inone or more of the housing, the first electronic module extension, orthe second electronic module extension to retain the electronic moduleextensions in the open or closed positions. In yet another embodiment,detents can be included within the hinge to provide a motion cessationfeature to allow the electronic module extension to be opened to any ofa predetermined number of angularly displaced orientations relative tothe housing.

From a combined mechanical and electrical perspective, in one embodimentan operational mode of the electronic module can be configured bypositioning the electronic module extensions in one or more predefinedangularly displaced orientations. As will be shown below, electronicmodules configured in accordance with embodiments of the invention canoperate in a variety of modes. Such modes include a desktop mode, atelephone mode, a wristwatch mode, a health monitoring mode, a clockmode, a calendar mode, a gaming mode, or a media player mode. This listis not exclusive, as others will be readily apparent to those ofordinary skill in the art having the benefit of this disclosure. A usercan cause the electronic module to enter a particular mode, in oneembodiment, by placing the electronic module extensions in apredetermined alignment. Illustrating by example, when the electronicmodule is configured to be worn on the wrist by pivoting the electronicmodule extensions to the open position, a control circuit disposedwithin the housing may cause the device to enter the health monitoringmode, a wrist watch mode, or a combination thereof. By contrast, whenone electronic module extension is folded to the closed position, thecontrol circuit may cause the electronic device to enter a music playermode. When both electronic module extensions are pivoted to the closedposition, the control circuit may cause the electronic device to enterthe desktop mode or calendar mode or clock mode, and so forth. Thesemodes are explanatory only, and are not intended to be limiting.

Turning now to FIG. 1, illustrated therein is one explanatory example ofan electronic device 100 suitable for use with presentation orientationmethods and systems described herein. As noted above, the methods andsystems for altering presentation orientation are well suited for mostany portable electronic device, including mobile communication devices,portable computers, and the like. For illustration purposes andsimplicity of discussion, the electronic device 100 used in many of thefigures is configured as a wearable electronic device. For example, theelectronic device 100 of FIG. 1 is configured as a wristwatch having anactive strap 102 and a detachable electronic module 101. This electronicdevice 100 is useful for discussion purposes because wearable devicesconfigured in accordance with embodiments described herein can performadditional functions that traditional electronic devices cannot.However, it will be clear to those of ordinary skill in the art havingthe benefit of this disclosure that the additional features are optionaland can be used in some applications, while the presentation orientationmanipulation techniques can be applied to simpler, non-wearable deviceswithout employing all of the advanced features of the illustrativewearable device.

As shown in FIG. 2, the detachable electronic module 101 can beselectively detached from the active strap 102 so as to be used as astand alone electronic device. For example, the detachable electronicmodule 101 can be configured with cellular communication capabilitiesand may be detached from the active strap 102 to be used more privatelyas a mobile telephone than if it were coupled to a wearer's wrist. Inother embodiments, the active strap 102 can optionally be configuredwith mechanically configurable characteristics such that it can be usedas a configurable stand when the electronic device 100 is placed on atable. Both the active strap 102 and the detachable electronic module101 can be configured as “active” devices. An active device refers to adevice that includes a power source and hardware. Active devices caninclude control circuits or processors as well.

In one or more embodiments, the detachable electronic module 101 can bedetached from the active strap 102 so that it can be coupled with, orcan communicate or interface with, other devices. For example, where thedetachable electronic module 101 includes wide area networkcommunication capabilities, such as cellular communication capabilities,the detachable electronic module 101 may be coupled to a folio ordocking device to interface with a tablet-style computer. In thisconfiguration, the detachable electronic module 101 can be configured tofunction as a modem or communication device for the tablet-stylecomputer. In such an application, a user may leverage the large screenof the tablet-style computer with the computing functionality of thedetachable electronic module 101, thereby creating device-to-deviceexperiences for telephony, messaging, or other applications. Thedetachable nature of the detachable electronic module 101 serves toexpand the number of experience horizons for the user.

Turning back to FIG. 1, in one embodiment the detachable electronicmodule 101 includes a display 103 configured to provide visual outputhaving a presentation orientation 104 associated therewith. Forillustration purposes, the presentation orientation 104 is shown as anarrow, which is pointing up. This constitutes a first presentationorientation. Where the arrow was pointing down, this would constitute asecond presentation orientation, and so forth. The visual output can betext, pictures, video, audio, or other content.

As will be shown in subsequent figures, in one or more embodiments, theelectronic device 100 can be configured with various combinations of thefollowing features: wide area network communication capabilities, e.g.,cellular or other mobile communication capabilities; local area networkcommunication capabilities, e.g., Bluetooth™ or other similarcommunication capabilities; voice call capabilities includingconventional phone functionality, speaker phone functionality, orprivate mode capabilities via a wired or wireless headset; one or morewellness sensors, such as heart rate sensors, temperature sensors, orsweat sensors; context sensors, such as accelerometers, globalpositioning sensors, microphones, local infrared sensors, local lightsensors, and local touch sensors; and other safety and security sensorsand applications. These features can be integrated into the detachableelectronic module 101, the active strap 102, or by way of a combinationof the two when coupling the detachable electronic module 101 to theactive strap 102 is both an electrical and mechanical coupling.

The detachable electronic module 101, in one embodiment, is equippedwith a first electronic module extension 107 and a second electronicmodule extension 108. The electronic module extensions 107,108 can becoupled to the housing of the detachable electronic module 101 by way ofhinge. Accordingly, the first electronic module extension 107 can behingedly coupled to a first side of the housing such that it extendsdistally from the first side of the housing, while the second electronicmodule extension 108 can be hingedly coupled to a second side of thehousing that different from the first side, such that it extendsdistally from the second side of the housing. The hinged attachmentallows the first electronic module extension 107 and the secondelectronic module extension 108 to selectively pivot from a closedposition, where the electronic module extensions 107,108 are disposedagainst a rear, major face of the housing, to an angularly displacedopen position extending distally outward from the housing.

The illustrative electronic device 100 of FIGS. 1 and 2 includes a formfactor that is thin, pleasing, functional, and practical. Exemplarydimensions of some of the components will aid in understanding the shapeand size of one explanatory embodiment. For instance, the display 103can be configured with a 1.6 inch diagonal dimension. The detachableelectronic module 101 can have a length 105 of about 62 millimeters, anda width of about 49 millimeters. (The term “about” is used to refer todimensions inclusive of manufacturing and component tolerances. Forexample, a measurement of 48.1 or 49.9 millimeters will be about 49millimeters when the manufacturing tolerances are plus or minus 1millimeter.) In this illustrative embodiment, the electronic moduleextensions 107,108 have a width 109 of about 42 millimeters, and alength 110 of between 20 and 40 millimeters, depending upon theapplication. An illustrative detachable electronic module 101 withcommunication capabilities, wellness detectors, and audio capabilitiescan be formed with a thickness (into the page) of about 10 millimeters.The length 111 of the active strap 102 can vary based upon targetwearer's wrist size or application.

Turning now to FIG. 3, illustrated therein is a schematic block diagramof various components and modules suitable for inclusion in thedetachable electronic module 101. It will be clear to those of ordinaryskill in the art having the benefit of this disclosure that thecomponents and modules can be used in different combinations, with somecomponents and modules included and others omitted. For altering thepresentation orientation (104) of visual output presented on the display103, the components of the display system can include a control circuit301 and the display 103. The other components or modules can be includedor excluded based upon need or application.

A control circuit 301 is coupled to the display 103. The control circuit301 can be operable with a memory 302. The control circuit 301, whichmay be any of one or more microprocessors, programmable logic,application specific integrated circuit device, or other similar device,is capable of executing program instructions and methods describedherein. The program instructions and methods may be stored eitheron-board in the control circuit 301, or in the memory 302, or in othercomputer readable media coupled to the control circuit 301. The controlcircuit 301 can be configured to operate the various functions of thedetachable electronic module 101, and also to execute software orfirmware applications and modules that can be stored in a computerreadable medium, such as memory 302. The control circuit 301 executesthis software or firmware, in part, to provide device functionality. Thememory 302 may include either or both static and dynamic memorycomponents, may be used for storing both embedded code and user data.One suitable example for control circuit 301 is the MSM7630 processormanufactured by Qualcomm, Inc. The control circuit 301 may operate oneor more operating systems, such as the Android™ mobile operating systemoffered by Google, Inc. In one embodiment, the memory 302 comprises an8-gigabyte embedded multi-media card (eMMC).

The control circuit 301, which in one embodiment is disposed in thecentral housing of the detachable electronic module 101 and not withineither the first electronic module extension 107 or the secondelectronic module extension 108, can be configured to alter an operatingmode of the electronic module to one of a plurality of functional modes.As noted above, these functional modes can include a desktop mode, atelephone mode, a wristwatch mode, a health monitoring mode, a clockmode, a calendar mode, a gaming mode, or a media player mode. As will bedescribed below, the control circuit 301 in one embodiment selects anoperational mode from these functional modes by detecting an angularlydisplaced orientation of the first electronic module extension 107, thesecond electronic module extension 108, or combinations thereof.

The display 103 is configured to provide visual output, images, or othervisible indicia to a user. In one embodiment, the display 103 comprisesa 1.6 inch organic light emitting diode (OLED) device. In oneembodiment, the display 103 comprises a touch sensor 312 to form touchsensitive display configured to receive user input across the surface ofthe display 103. The display 103 can also be configured with a forcesensor 310. Where configured with both a touch sensor 312 and forcesensor 310, the control circuit 301 can determine not only where theuser contacts the display 103, but also how much force the user employsin contacting the display 103. Where configured with a force sensor 310but no touch sensitive capabilities, the display 103 can be used as alarge “push button” or input control for the detachable electronicmodule 101. In one embodiment, explained in more detail below withreference to FIG. 15, the outer lens of the display 103 can beconfigured with piezoelectric sensors 315 or other actuators to be usedas both an input device and an acoustic transducer.

The touch sensor 312 can include a capacitive touch sensor, an infraredtouch sensor, or another touch-sensitive technology. Capacitivetouch-sensitive devices include a plurality of capacitive sensors, e.g.,electrodes, which are disposed along a substrate. Each capacitive sensoris configured, in conjunction with associated control circuitry, e.g.,control circuit 301 or another display specific control circuit, todetect an object in close proximity with—or touching—the surface of thedisplay 103 or the housing of the detachable electronic module 101 byestablishing electric field lines between pairs of capacitive sensorsand then detecting perturbations of those field lines. The electricfield lines can be established in accordance with a periodic waveform,such as a square wave, sine wave, triangle wave, or other periodicwaveform that is emitted by one sensor and detected by another. Thecapacitive sensors can be formed, for example, by disposing indium tinoxide patterned as electrodes on the substrate. Indium tin oxide isuseful for such systems because it is transparent and conductive.Further, it is capable of being deposited in thin layers by way of aprinting process. The capacitive sensors may also be deposited on thesubstrate by electron beam evaporation, physical vapor deposition, orother various sputter deposition techniques. For example, commonlyassigned U.S. patent application Ser. No. 11/679,228, entitled“Adaptable User Interface and Mechanism for a Portable ElectronicDevice,” filed Feb. 27, 2007, which is incorporated herein by reference,describes a touch sensitive display employing a capacitive sensor.

The force sensor 310 can take various forms. For example, in oneembodiment, the force sensor 310 comprises resistive switches or a forceswitch array configured to detect contact with either the display 103 orthe housing of the detachable electronic module 101. An “array” as usedherein refers to a set of at least one switch. The array of resistiveswitches can function as a force-sensing layer, in that when contact ismade with either the surface of the display 103 or the housing of thedetachable electronic module 101, changes in impedance of any of theswitches may be detected. The array of switches may be any of resistancesensing switches, membrane switches, force-sensing switches such aspiezoelectric switches, or other equivalent types of technology. Inanother embodiment, the force sensor 310 can be capacitive. One exampleof a capacitive force sensor is described in commonly assigned, U.S.patent application Ser. No. 12/181,923, filed Jul. 29, 2008, publishedas US Published Patent Application No. US-2010-0024573-A1, which isincorporated herein by reference. In yet another embodiment,piezoelectric sensors 315 can be configured to sense force as well. Forexample, where coupled with the lens of the display 103, thepiezoelectric sensors 315 can be configured to detect an amount ofdisplacement of the lens to determine force. The piezoelectric sensors315 can also be configured to determine force of contact against thehousing of the detachable electronic module 101 rather than the display103.

A mobile communication circuit 303 can be included to provide wide areacommunication capabilities. Where included, the mobile communicationcircuit 303 is operable with the control circuit 301, and is used tofacilitate electronic communication with various networks, such ascellular networks, data networks, or the Internet. Note that it ispossible to combine the control circuit 301, the memory 302, and themobile communication circuit 303 into a single device or into deviceshaving fewer parts while retaining the functionality of the constituentparts.

The mobile communication circuit 303, which may be one of a receiver ortransmitter, and may alternatively be a transceiver, operates inconjunction with the control circuit 301 to electronically communicatethrough a communication network. For example, in one embodiment, themobile communication circuit 303 can configured to communicate through atraditional cellular network, such as a Code Division Multiple Access(CDMA) network or Global System for Mobile communication (GSM) network.Other examples of networks with which the communication circuit maycommunicate include Push-to-Talk (PTT) networks, proprietary networks,dual band CDMA networks, or Dual Band Universal MobileTelecommunications System (UMTS) networks, and direct communicationnetworks. The mobile communication circuit 303 can be configured toprovide messaging functionality to the detachable electronic module 101.In one or more embodiments, the detachable electronic module cancommunicate with one or more social networking applications through themobile communication circuit 303 as well. News feeds and other data canbe received through the mobile communication circuit 303. Moreover,context and location sensitive notifications can be sent and receivedvia the mobile communication circuit 303.

A battery 304 or other energy source can be included to provide powerfor the various components of the detachable electronic module 101.While a battery 304 is shown in FIG. 3, it will be obvious to those ofordinary skill in the art having the benefit of this disclosure thatother energy storage deices can be used instead of the battery 304,including a fuel container or an electrochemical capacitor.

In one or more embodiments, the battery 304 disposed within the firstelectronic module extension 107, the second electronic module extension108, or combinations thereof, and not within the central housing of thedetachable electronic module 101. In such a configuration, the battery304 is configured to deliver energy to electronic components, e.g., thecontrol circuit 301, memory 302, display 103, etc., each of which isdisposed only within the central housing of the detachable electronicmodule 101.

One or more microphones 305 can be included to receive voice input,voice commands, and other audio input. A single microphone can beincluded. Optionally, two or more microphones can be included forselective beam steering. For example a first microphone can be locatedon a first side 330 of the detachable electronic module 101 forreceiving audio input from a first direction 332. Similarly, a secondmicrophone can be placed on a second side 331 of the detachableelectronic module 101 for receiving audio input from a second direction333. As will be described below, an infrared sensor 314, light sensor306, or other sensor can detect a direction in which a user is located.The control circuit 301 can then select between the first microphone andthe second microphone to beam steer audio reception toward the user.Alternatively, the control circuit 301 processes and combines thesignals from two or more microphones to perform beam steering. The oneor more microphones 305 can be used for voice commands. When alteringthe presentation orientation of information presented on the display,the one or more microphones 305 can be configured to be responsive tothe control circuit 301. Accordingly, the control circuit 301 can switchbetween microphones upon altering the presentation orientation inresponse to the user input.

A light sensor 306 is configured to detect changes in optical intensity,color, light, or shadow in the near vicinity of the detachableelectronic module 101. For example, the light sensor 306 can beconfigured as an image sensing device that captures successive imagesabout the device and compares luminous intensity, color, or otherspatial variations between images to detect motion or the presence of anobject near the detachable electronic module 101. Such sensors can beuseful in determining at which side of the detachable electronic module101 a user is standing. An infrared sensor 314 can be used inconjunction with, or in place of, the light sensor 306. The infraredsensor 314 can be configured to operate in a similar manner, but on thebasis of infrared radiation rather than visible light. The light sensor306 and/or infrared sensor 314 can be used for gesture commands, as willbe described with reference to subsequent figures.

A near field communication circuit 307 can be included for communicationwith local area networks. Examples of suitable near field communicationcircuits include Bluetooth communication circuits, IEEE 801.11communication circuits, infrared communication circuits, magnetic fieldmodulation circuits, and Wi-Fi circuits.

A global positioning system device 308 can be included for determiningwhere the detachable electronic module 101 is located. (Note that theglobal positioning system device 308 can also be used to determine thespatial orientation of the detachable electronic module 101 inthree-dimensional space by determining the change in position of thedevice relative to the earth.) The global positioning system device 308is configured for communicating with a constellation of earth orbitingsatellites or a network of terrestrial base stations to determine anapproximate location. Examples of satellite positioning systems suitablefor use with embodiments of the present invention include, among others,the Navigation System with Time and Range (NAVSTAR) Global PositioningSystems (GPS) in the United States of America, the Global OrbitingNavigation System (GLONASS) in Russia, and other similar satellitepositioning systems. The satellite positioning systems based locationfixes of the global positioning system device 308 autonomously or withassistance from terrestrial base stations, for example with assistancefrom a cellular communication network or other ground based network, oras part of a Differential Global Positioning System (DGPS), as is wellknown by those having ordinary skill in the art. While a globalpositioning system device 308 is one example of a location determinationmodule, it will be clear to those of ordinary skill in the art havingthe benefit of this disclosure that other location determinationdevices, such as electronic compasses or gyroscopes, could be used aswell.

A user interface 309 can be included. As noted above, in one embodiment,the display 103 is configured as a touch sensitive display, andaccordingly functions as a user interface in and of itself. However,some applications will be better served with additional user interfacecomponents as well. The user interface 309, where included, can beoperable with the control circuit 301 to deliver information to, andreceive information from, a user. The user interface 309 can include akeypad 335, navigation devices, joysticks, rocker switches, slider pads,buttons, or other controls, and optionally a voice or touch commandinterface. These various components can be integrated together.

In one or more embodiments, the lens of the display 103 can beconfigured as a lens transducer 311 to deliver audio output to a user.While this will be described in more detail with reference to FIG. 15below, piezoelectric transducers can be operably disposed with a lens ofthe display 103. Actuation of the piezoelectric transducers can causethe lens of the display 103 to vibrate, thereby emitting acousticoutput. An example of a piezo-driven lens speaker is described incommonly assigned, pending U.S. Ser. No. 12/967,208, filed ______,entitled “______,” which is incorporated herein by reference.

An accelerometer 313 can be included to detect motion of the detachableelectronic module 101. The accelerometer 313 can also be used todetermine the spatial orientation of the detachable electronic module101 in three-dimensional space by detecting a gravitational direction.In addition to, or instead of, the accelerometer 313, an electroniccompass can be included to detect the spatial orientation of thedetachable electronic module 101 relative to the earth's magnetic field.Similarly, one or more gyroscopes can be included to detect rotationalmotion of the detachable electronic module 101. The gyroscope can beused to determine the spatial rotation of the detachable electronicmodule 101 in three-dimensional space.

Where the detachable electronic module 101 is configured as a wellnessdevice, or is capable of operating in a health monitoring mode orphysical safety device, one or more wellness sensors 334 can be includedas well. Examples of wellness sensors are described in commonly assignedU.S. patent application Ser. No. 10/396,621, filed Mar. 24, 2003,published as US Published Patent Application No. 2004/0015058, which isincorporated herein by reference.

For example, a heart monitor 316 can be configured to employ EKG orother sensors to monitor a user's heart rate. The heart monitor 316 caninclude electrodes configured to determine action potentials from theskin of a user. A temperature monitor 317 can be configured to monitorthe temperature of a user. A pulse monitor 318 can be configured tomonitor the user's pulse. The pulse monitor 318 lends itself to thewristwatch configuration of the electronic device (100) of FIG. 1because the wrist serves as an advantageous location from which tomeasure a person's pulse.

A moisture detector 319 can be configured to detect the amount ofmoisture present on a person's skin. The moisture detector 319 can berealized in the form of an impedance sensor that measures impedancebetween electrodes. As moisture can be due to external conditions, e.g.,rain, or user conditions, perspiration, the moisture detector 319 canfunction in tandem with ISFETS configured to measure pH or amounts ofNaOH in the moisture or a galvanic sensor 320 to determine not only theamount of moisture, but whether the moisture is due to external factors,perspiration, or combinations thereof.

The medical history of a user, as well as the determinations made by thevarious wellness sensors 334, can be stored in a medical profile 321.Periodic updates can be made to the medical profile 321 as well. Themedical profile 321 can be a module operable with the control circuit301. Such modules can be configured as sets of instructions stored inthe memory 302 that are usable by the control circuit 301 to execute thevarious wellness monitoring functions of the detachable electronicmodule 101. Alternatively, the modules could be configured in hardware,such as through programmable logic. The wellness sensors 334 shown inFIG. 3 are illustrative only. Embodiments of the present invention mayuse various combinations of wellness sensors 334, including subsets ofthe wellness sensors 334 shown in FIG. 3. Further, other modules may beadded to further increase device functionality. The wellness sensors 334can be used to provide the user with a sensor-based health and wellnessdata assessment. The wellness sensors 334 can be used in conjunctionwith the medical profile 321 to provide context sensitiverecommendations on the display 103.

Turning now to FIG. 4, illustrated therein is a cut-away view of thedetachable electronic module 101 illustrating how some of the componentsof FIG. 3 may be disposed within the housing of the detachableelectronic module 101. The battery (304) in the embodiment of FIG. 4comprises a first cell 407 disposed in a first electronic moduleextension 107 and a second cell 408 disposed in a second electronicmodule extension 108. All other electrical components, such as thecontrol circuit 301, are disposed within a central housing of thedetachable electronic module 101, with the exception of any conductorsor connectors, safety circuits, or charging circuits used or required todeliver energy from the first cell 407 and second cell 408 to theelectronic components disposed within the central housing. In thisillustrative embodiment, the first cell 407 and second cell 408 eachcomprise 400 mAh lithium cells. Where the detachable electronic module101 is configured for communication with both wide area networks, e.g.,cellular networks, and local area networks, e.g., WiFi networks, boththe first cell 407 and the second cell 408 can be included. However, insome embodiments where only local area network communication or nocommunication capability is included, one of the first cell 407 orsecond cell 408 may be omitted. As noted above, the first cell 407 andsecond cell 408 can be coupled in parallel to provide higher peak pulsecurrents. Alternatively, the first cell 407 and the second cell 408 canbe coupled in series when there is no high current demand. One or moreswitches can be used to selectively alter the coupling of the first cell407 and second cell 408 in the series/parallel configurations.

The mobile communication circuit 303 is disposed at a first end of thedetachable electronic module 101. The near field communication circuit307 can be disposed on a side of the detachable electronic module 101opposite the mobile communication circuit 303. The global positioningsystem device (308), where included, can also be disposed on a sideopposite the mobile communication circuit 303. In this illustrativeembodiment, the global positioning system device (308) is displaced fromthe near field communication circuit 307 to avoid interference. Thelight sensor 306 and/or infrared sensor 314 can be disposed on a side ofthe device.

The microphones (305) in this embodiment comprise a first microphone 405disposed on a first side of the detachable electronic module 101 and asecond microphone 406 disposed on a second side of the detachableelectronic module 101 that is opposite the first side. As noted above,multiple microphones can be included to receive voice input, voicecommands, and other audio input. In this embodiment, the firstmicrophone 405 and second microphone 406 can be used for selective beamsteering. The infrared sensor 314, light sensor 306, or other sensor candetect a directional position of a user. The control circuit 301 canthen select between the first microphone 405 and the second microphone406 to beam steer audio reception toward the user.

Turning now to FIGS. 5 and 6, illustrated therein are additionalinternal components associated with one explanatory detachableelectronic module 101 configured in accordance with one or moreembodiments of the invention. FIG. 5 illustrates an exploded view, whileFIG. 6 illustrates a sectional view.

The detachable electronic module 101 includes a housing 501 configuredto carry internal components. This illustrative housing 501 is curvedand contoured so as to forma a wearable housing, in that it can becoupled to either a passive or active strap and worn about a wrist, arm,or leg. Alternatively, it could be coupled about a waist as well. In oneembodiment, the housing 501 and a cover layer 502 of the displayassembly bound the internal components. An optional mechanical upperhousing 503 can also be used to retain the cover layer 502 within thehousing 501. (The optional mechanical upper housing 503 is not shown inFIG. 6.)

The cover layer 502 can be a substrate manufactured from thin plasticfilm, sheet plastic, or reinforced glass. The cover layer 502 serves asa fascia member for the detachable electronic module 101. A “fascia” isa covering or housing, which may or may not be detachable, for anelectronic device like the detachable electronic module 101 of FIGS. 5and 6. To provide ornamentation, text, graphics, and other visualindicators, the cover layer 502, in one embodiment, includes printingdisposed on the rear face. Selective printing on the cover layer 502 maybe desirable, for instance, around the perimeter of the cover layer 502to cover electrical traces connecting internal components. Printing maybe desired on the front face of the cover layer 502 for various reasonsas well. For example, a subtle textural printing or overlay printing maybe desirable to provide a translucent matte finish atop the detachableelectronic module 101. Such a finish is useful to prevent cosmeticblemishing from sharp objects or fingerprints. By printing only on therear face, the front face can remain smooth and glossy. The cover layer502 may also include an ultra-violet barrier as well. Such a barrier isuseful both in improving the visibility of the display module 504 and inprotecting internal components of the detachable electronic module 101.As noted above, the cover layer 502 can include a plurality of indiumtin oxide or other electrodes, which function as a capacitive sensor, tocovert the display to a touch-sensitive display.

Beneath the cover layer 502 is the display module 504, which in thiscase is an OLED display module. The display module 504 is configured toprovide visual output having a presentation orientation through thecover layer 502 to the user.

As noted above, in one or more embodiments, the display (103) or coverlayer 502 can be can be used as a user input and as a transducer foracoustic output. In some embodiments, the cover layer 502, displaymodule 504, or combinations thereof will be moveable relative to thehousing 501. In some embodiments, an acoustic roll of compliant material505 can be disposed between the cover layer 502 and the housing 501. Theinclusion of the acoustic roll facilitates small movement of the coverlayer 502, display module 504, or combinations thereof relative to thehousing 501. A design gap 605 can be included between the cover layer502 and the housing 501 for insertion of the acoustic roll of compliantmaterial 505 and to facilitate travel of the cover layer 502 relative tothe housing 501. In embodiments that have an exposed display (103) withno cover layer 502, the display (103) can be attached to the acousticroll of compliant material 505 in place of the cover layer 502. In theseembodiments, the movable display module would serve the as the userinput and transducer for acoustic output.

A circuit carrier 506 can then include the control circuit (301) andother electronic circuitry components and modules. In one embodiment,the circuit carrier 506 comprises a printed circuit board manufacturedfrom FR-4 fiberglass. In another embodiment, the circuit carrier 506comprises a flexible substrate disposed about flexible conductors, whichis known in the art as a “flex” circuit. The circuit carrier 506 caninclude components disposed on the top and bottom sides. Alternatively,the circuit carrier 506 can have components disposed on a single side toconserve cost. The circuit carrier 506 can comprise one or moresubstrates that are coupled together with electrical conductors, wires,or other flex circuits.

Where the cover layer 502 is used in conjunction with piezoelectricdevices 507, a piezo frame 508 can be used as a mechanical supportextending from the piezoelectric devices 507 and the cover layer 502.When the piezoelectric devices 507 are actuated, the piezo frame 508transfers force to the cover layer 502 to make it move in response tothe forces generated by the piezoelectric devices 507. Alternatively,when a user engages the cover layer 502 to use it as a control input,user exerted force is transferred through the piezo frame 508 to thepiezoelectric devices 507, which function as an input sensor in thismode.

The piezoelectric devices 507 can be configured as disks or pills asshown in FIG. 5. Alternatively, the piezoelectric devices 507 can beconfigured as bendable elements bonded to the piezo frame 508. In thecase where piezoelectric disks are couple to the piezo frame 508, oneportion of the piezoelectric disks can be coupled to the piezo frame 508while another portion of the piezoelectric disks is coupled to thehousing 501 or another portion of detachable electronic module 101 thatis more massive than the cover layer 502. Alternatively thepiezoelectric disks can be disposed between the cover layer 502 and thepiezo frame 508, reversing the order of the components, but stillproviding the same effective functionality. This latter embodimentserves as an effective mechanical grounding for the piezoelectricsystem. In an embodiment where the piezoelectric devices 507 arebendable elements bonded to the piezo frame 508, the bendable elementscan be bonded only to the piezo frame 508, with the frame being coupledto both the cover layer 502 and the housing 501.

Turning to FIG. 7 illustrated therein are components that can beincluded in the active strap 102. Note that in many embodiments, thedetachable electronic module (101) can be coupled to passive straps orattachments to form a wearable electronic device. In one or moreembodiments, functionality can be increased by providing an active strap102 that also includes a power source and hardware components. Thecomponents shown in FIG. 7 provide an illustration of components thatcan be included with the active strap 102. However, as with the modulesshown in FIG. 3, the active strap 102 can include subsets of themodules, with only those modules being included as required by aparticular application.

The active strap 102 can include its own control circuit 701. Thecontrol circuit 701 can be operable with a memory 702. The controlcircuit 701, which may be any of one or more microprocessors,programmable logic, application specific integrated circuit device, orother similar device, is capable of executing program instructionsassociated with the functions of the active strap 102. The programinstructions and methods may be stored either on-board in the controlcircuit 701, or in the memory 702, or in other computer readable mediacoupled to the control circuit 701.

The active strap 102 can include a display 703. In one embodiment, thedisplay 703 comprises one or more flexible display devices. Since theactive strap 102 can be configured as a wristband for a wristwatch-typewearable device, flexible displays disposed on the active strap 102 can“wrap” around the wearer's wrist without compromising operationalperformance. While the display 703 can include non-flexible displays aswell, the inclusion of flexible display devices not only increasescomfort for the wearer but also allows the display 703 to be larger aswell. The display 703 can be configured to be touch sensitive also,thereby allowing the display 703 to be used as a control input. Thedisplay is configured to provide visual output, images, or other visibleindicia to a user. The display 703 can also be configured with a forcesensor. Where configured with both, the control circuit 701 candetermine not only where the user contacts the display 703, but also howmuch force the user employs in contacting the display 703. Whereconfigured with a force sensor only, the display 703 can be used as alarge “push button” or input control.

A battery 704 or other energy source can be included to provide powerfor the various components of the active strap 102. In one or moreembodiments, the battery 704 is selectively detachable from the activestrap 102. Charging circuitry 705 can be included in the active strap102 as well. The charging circuitry 705 can include overvoltage andovercurrent protection. In one embodiment, the battery 704 is configuredas a flexible lithium polymer cell.

One or more microphones 706 can be included to receive voice input,voice commands, and other audio input. A single microphone can beincluded. Optionally, two or more microphones can be included forselective beam steering. As with the detachable electronic module (101)described above, a first microphone can be located on a first side ofthe active strap 102 for receiving audio input from a first direction,while a second microphone can be placed on a second side of the activestrap 102 for receiving audio input from a second direction. In responseto a sensor, perhaps located in the detachable electronic module (101),a user location direction can be determined. The control circuit 701 canthen select between the first microphone and the second microphone tobeam steer audio reception toward the user. Alternatively, the controlcircuit 701 can employ a weighted combination of the microphones to beamsteer audio reception toward the user.

A near field communication circuit 707 can be included for communicationwith local area networks. A global positioning system device 708 can beincluded for determining location information. One or more audio outputdevices 709 can be included to deliver audio output to a user.Piezoelectric devices 710 can be configured to both receive input fromthe user and deliver haptic feedback to the user.

Where desired, one or more wellness sensors 711 can be included as well.As described above, the wellness sensors 711 can include a heartmonitor, moisture detector, temperature monitor, pulse monitor, galvanicdevices, and so forth.

Turning now to FIG. 8, illustrated therein is a cut-away view of theactive strap 102 that demonstrates illustrative locations of some of thecomponents shown in FIG. 7. In this illustrative embodiment, the display(703) comprises a first display 803 disposed on a first side of theactive strap 102 and a second display 804 disposed on a second side ofthe active strap 102. The first display 803 and the second display 804are flexible displays, and cover substantial portions of the outersurface of the upper face of the active strap 102. Disposition of thedisplays in this arrangement lends itself to interesting applications.For example, when used with a light sensor (306) of a detachableelectronic module (101) coupled to the active strap, the displays canpresent a color that is complementary to the colors worn by the user,thereby transforming the active strap 102 into a fashion accessory.Alternatively, the displays can present data, images, video, or otherindicia to the user.

The battery 704 in this illustrative embodiment has been disposedbeneath an attachment bay 801. The attachment bay 801 is configured forattachment to other electronic devices, one example being the detachableelectronic module (101) of FIG. 4. Where included, the near fieldcommunication circuit 707 can be disposed within the attachment bay 801as well. Alternatively, the near field communication circuit 707 can bedisposed in the outer portions of the active strap 102.

Turning now to FIG. 9, illustrated therein is another embodiment of anelectronic device 900 configured in accordance with embodiments of thepresent invention. The electronic device 900 is configured as a wearabledevice. A detachable electronic module 901 is coupled to an active strap902 to form a wrist wearable device. The illustrative electronic device900 of FIG. 9 includes a mobile communication circuit (303), a touchsensitive display 903, wellness sensors (334), a near fieldcommunication circuit (307), a global positioning system device (308),an infrared sensor (314), twin microphones configured for selective beamsteering, and a cover layer configured with piezoelectric sensors (315)so as to function as an acoustic transducer and input control device.Accordingly, the electronic device 900 can function in a telephone modeto not only serve as a personal communication device akin to a mobiletelephone, but can also function in a health monitoring mode to alsoserve as a personal safety and security device capable of detectingfalls, user accidents, user drowsiness, user sleep and sleep patterns.Moreover, the electronic device 900 is capable of sending and receivingemergency alert communication messages, as well as delivering alertnotifications to the user. In one or more embodiments, the electronicdevice 900 can be configured to communicate with social networks toprovide automatic wellness and other updates to friends or family. Thewearable electronic device 900 functions as a wearable wirelesscommunication device that is compact and includes wellness sensingcapabilities. The electronic device 900 has an efficient, compact designwith a simple user interface configured for efficient operation with onehand (which is advantageous when the electronic device 900 is worn onthe wrist).

In addition to the touch sensitive input of the touch sensitive display903, the electronic device 900 is further equipped with an accelerometer(313) that can detect movement. Accordingly, when the electronic device900 is worn on a wrist, the user can make gesture commands by moving thearm in predefined motions. Additionally, the user can deliver voicecommands to the electronic device 900 via the twin microphones.

The user interface of the electronic device 900 is specially designedfor a small screen. It included an intuitive touch interface. When thepiezoelectric sensors (315) in conjunction with the cover layer of thetouch sensitive display 903 are utilized as a touch interface, specialfunctions can be realized. For example, the cover layer can be pressedfor a short time, e.g., less than two seconds, to power on and off theelectronic device 900. Alternatively, the cover layer can be pressed fora long time, e.g., more than two seconds, to perform a special function,such as transmission of an emergency message.

When the touch sensitive display 903 is configured as a touch sensitivedisplay, control input can be entered in some embodiments with a singleswiping action across the surface of the touch sensitive display 903.When operating in conjunction with the piezoelectric sensors (315), thetouch sensitive display 903 can deliver intelligent alerts, acoustics,and haptic feed back in addition to visual output. In one or moreembodiments, the touch sensitive display 903 is configured to altermagnification of the visual output for special applications. Forinstance, the touch sensitive display 903 can alter the magnification ofa keypad during mobile communication dialing operations.

Using the near field communication circuit (307), the electronic device900 can communicate with other electronic devices to provide “device todevice” connectivity. For example, the electronic device 900 can link toa tablet-style computer to permit viewing of the visual output of thetouch sensitive display 903 on a larger screen. The electronic device900 can further serve as a communication portal for the tablet stylecomputer, providing telephony functionality, messaging functionality,and notification functionality for the tablet-style computer.

As the electronic device 900 is configured with a small form factor in awearable configuration, it provides advantages over prior art devices.For example, with prior art devices, a user employing a tablet-stylecomputer frequently had to carry a mobile telephone to providecommunication capability for the tablet-style computer. The wearablenature of the electronic device 900 alleviates the need to carry a largecommunication device for device-to-device connectivity with portablecomputers or tablet style computers. Moreover, the wearable nature ofthe electronic device 900 is compact and simple for a user to carry.

The inclusion of wellness sensors (334) provides advantageousapplications in the area of wellness and health. For example, themedical profile (321) permits a user to store a medical history orwellness profile in the electronic device 900. Applications operable onthe electronic device 900 can then draw on this information to providewellness applications that are specifically tailored to the wearer.Additionally, sensors like the heart monitor (316), pulse monitor (318),and temperature monitor (317) can continually monitor vital signals ofthe user while the electronic device 900 is worn. By maintaining arecord of this monitoring in the medical profile (321), the electronicdevice can provide a wellness assessment by analyzing the data. Sleepcan be detected based upon pulse and temperature. Additionally,high-risk situations can be detected from elevated pulse, heartbeat, andexcessive perspiration.

Applications operable on the electronic device 900 can provide timelywellness and health reminders, such as when a user should ingestmedicine or when the user should exercise. Further, wellness outcomes,such as the results of an exercise session, can be presented on thetouch sensitive display 903. The wellness sensors (334) can beconfigured to monitor vital signals only upon predetermined criteria.For example, when the moisture detector (319) detects moisture, thewellness sensors (334) may presume the user is exercising and actuatevital sign monitoring. The wellness sensors (334) can be configured tomake wellness recommendations based upon location, history, and/oractivity. The wellness sensors (334) can be configured to provide earlywarnings that anticipate health events based upon data detected usingonboard sensors. The wellness sensors (334) can be configured toautomatically journal daily physical and wellness activity. The wellnesssensors (334) can be configured to provide real time updates to trustedfamily members, friends, or medical service providers.

The wellness sensors (334) can be configured to automatically delivermessages to third parties, e.g., doctors, family members, or friends,when abnormal wellness conditions are detected. As noted above, in oneor more embodiments, a user can send such a message by pressing thecover layer of the touch sensitive display 903 for a predetermined time.The wellness sensors (334) can be configured to detect falls, autoaccidents, extended lack of motion of a wearer, or sleep. This will bedescribed in more detail with reference to FIG. 24 below. In oneembodiment, the wellness sensors (334) can be configured to provideawakening alerts to the user when drowsiness or sleep is detected.

Turning now to FIG. 10, the detachable nature of the detachableelectronic module 901 from the active strap 902 is shown. As will bedescribed below with reference to FIG. 42, in one embodiment thedetachable electronic module 901 can be detached from the active strap902 by “hyper pivoting” the electronic module extensions 1007,1008relative to the housing of the detachable electronic module 901 awayfrom the active strap 902.

In this illustrative embodiment, the electronic module extensions1007,1008 are non-planar, in that they are curved in cross section. Thisgeometric configuration provides a wearable configuration for thedetachable electronic module 901 in that the non-planar geometries ofthe electronic module extensions 1007,1008 are complementary to theshape of a wearer's arm. Where this is the case, energy storage devicesdisposed within the electronic module extensions 1007,1008 can benon-planar as well.

In FIG. 10, the detachable electronic module 901 has been released fromthe attachment bay 1001, thus converting it to a stand-alone device thatcan be used individually by the user or docked for use with otherdevices. In addition to providing wearable capabilities for the overallelectronic device 900, the active strap 902 can be used for a stand.Since it is an active device with hardware and a power source, theactive strap 902 can remain on the wrist to monitor wellness or otherconditions while the detachable electronic module 901 is not connected.Upon reconnection, the detachable electronic module 901 can retrievesuch monitored data and process it or communicate it as directed by aparticular application.

Turning now to FIG. 11, the detachable electronic module 901 has beenrotated to reveal electrical couplings 1101,1102,1103,1104 that allowthe detachable electronic module 901 and the active strap 902 to work intandem. In this illustrative embodiment, the attachment bay 1001includes electrical couplings 1101,1102 that mate with complementaryelectrical couplings 1103,1104 disposed on the electronic moduleextensions 1007,1008. The location of these electrical couplings1101,1102,1103,1104 is illustrative only. Other electrical couplingembodiments will be described below.

Turning to FIG. 12, the detachable electronic module 901 is shown byitself with one example of visual output 1201 being presented on thetouch sensitive display 903. The visual output 1201 in this embodimentis a telephone dialer, as the detachable electronic module 901 isoperating in a telephone mode. As noted above, in one or moreembodiments, the control circuit (301) of the detachable electronicmodule 901 can be configured to alter one of a color, a resolution, ascaling, an operating mode, or a magnification of the visual output1201. For example, one or more of these characteristics can be alteredwhen the control circuit (301) alters altering the presentationorientation of the visual output 1201 in response to the user input.

This can be understood with a simple use case. Presume that a user iswearing the detachable electronic module 901 on his wrist. A friend asksthe user to dial a local restaurant. The friend knows the number, butthe user does not. Rather than the friend having to say the number tothe user, the user may simply make a gesture, such as a swipe of his armtowards the friend. This gesture, sensed by the accelerometer (313) is auser input. Upon detecting this user input, a presentation moduleoperable with the display can alter a presentation orientation of visualoutput 1201 from an initial orientation, shown in FIG. 12, to a secondorientation, which may be rotated a predetermined rotation amount, e.g.,180 degrees from the initial orientation. The friend can then dial thenumber using the telephone dialer shown in FIG. 12. When the mobilecommunication circuit (303) makes a connection with the restaurant, thisrepresents an event occurring in the absence of further user input.Accordingly, the presentation module can revert the presentationorientation to the initial orientation, thus indicating to the user thata call has been established. In addition, the presentation module maypresent a prompt 1202 on the touch sensitive display 903 when the callwas connected.

Now suppose that both the friend and user need to speak with therestaurant. In one embodiment, the user may employ gestures to make thecommunication more efficient. For example, during the call, when it isthe friend's turn to speak, the user may make the same arm gesture ofswiping his arm towards the friend. In one embodiment, two speakers1203,1204 are provided, each having a differently oriented acousticoutput cone. The two speakers 1203,1204 thus form a directable audiooutput. When the user makes the gesture, the control circuit (301) canfurther to redirect output audio in addition to altering thepresentation orientation. The same can occur with multiple microphones.The control circuit (301) can switch between audio input devices uponaltering the presentation orientation in response to the user input.

Turning to FIG. 13, illustrated therein is an optional mechanicalfeature associated with one detachable electronic module 1301 configuredin accordance with one or more embodiments of the invention. As shown inFIG. 13, the electronic module extensions 1307,1308 are coupled to thedetachable electronic module 1301 with folding hinges and have beenfolded 1302,1303 about the rear side of the detachable electronic module1301. This position is referred to a “closed” position because theelectronic module extensions 1307,1308 are disposed against a majorface, i.e., the back surface, of the housing of the detachableelectronic module 1301. This collapsible feature allows the detachableelectronic module 1301 to become a more compact device when being usedin the absence of a passive or active strap. Additionally, as will bedescribed in more detail below, the collapsible feature can allow a userto alter the operational modes of the detachable electronic module 1301by moving, i.e., pivoting or rotating, the electronic module extensions1307,1308 relative to the central housing of the detachable electronicmodule 1301.

In this illustrative embodiment, each electronic module extension1307,1308 is equipped with pivoting power and ground contacts so thatpower from the cells disposed within the electronic module extensions1307,1308 is delivered to the control circuit and other components inthe detachable electronic module 1301 regardless of their radialorientation relative to the detachable electronic module 1301. In thisillustrative embodiment, the detachable electronic module 1301 has athickness 1309 of between twenty and thirty millimeters.

While the electronic module extensions 1307,1308 are shown completelyfolded in FIG. 13, it should be noted that the folding hinges can beconfigured to be resistive so as to be pivotable to any number ofrotational orientations as desired by a user. For example, eachelectronic module extension 1307,1308 can be rotated halfway so as toserve as a stand when the detachable electronic module 1301 is placed onits side. In one or more embodiments, the electronic module extensions1307,1308 are coupled to the central housing of the detachableelectronic module with a détented hinge that provides pseudo mechanicalstops so that the electronic module extensions 1307,1308 can be easilystopped at a variety of pre-defined angularly displaced orientationsrelative to the central housing of the detachable electronic module1301. In such an embodiment, the detented hinge comprises a plurality ofdetent stops configured to hold the one or both of the first electronicmodule extension 1307 or the second electronic module extension 1308 inone of a plurality of angularly displaced alignments relative to thehousing.

Turning to FIG. 14, illustrated therein are the detachable electronicmodule 1301 of FIG. 13 and an electronic device 1400 placed on a table1410. FIG. 14 illustrates a few of the many options for using theelectronic devices configured in accordance with embodiments of theinvention when not being worn. The electronic module extensions1307,1308 have been folded about detachable electronic module 1301. Thedetachable electronic module 1301 has then been placed face up, witheach electronic module extension 1307,1308 serving as a stand. Thisconfiguration can be useful, for example, when multiple people are usingthe detachable electronic module 1301 as a speakerphone during a groupcall. Further, the active strap to which the detachable electronicmodule 1301 was coupled can remain on the wrist performing wellnessmonitoring. With electronic device 1400, the active strap 1402 has beenstraightened from its wearable configuration to serve as a stand. Thisconfiguration can be useful, for example, when using the electronicdevice 1400 as an alarm clock.

Turning now to FIG. 15, a detachable electronic device 1501 havingpiezoelectric devices 1515 configured work with the cover layer 1502 ofthe display to provide input and output capabilities. Piezo frameelements 1516 function as mechanical couplers between the cover layer1502 and the piezoelectric devices 1515. The control circuit disposedwithin the detachable electronic device 1501 is operable with thepiezoelectric devices 1515. The control circuit can actuate thepiezoelectric devices 1515 to employ them as output devices.Alternatively, when forces act upon the piezo frame elements 1516, thoseforces are transferred to the piezoelectric devices 1515, therebydelivering signals to the control circuit. Accordingly, thepiezoelectric devices 1515 can be used as either input or outputdevices.

The inclusion of the piezoelectric devices 1515 provides manyadvantageous functions to the detachable electronic device 1501. Asnoted above, when the cover layer 1502 is touched or pressed by a user,the cover layer 1502 becomes an input control device for receiving userinput. The piezoelectric devices 1515 can sense this input and deliver acorresponding signal to the control circuit. By using multiplepiezoelectric devices 1515 that are spread out within the detachableelectronic device 1501, the signals can be read individually todetermine an approximate location along the cover layer 1502 contactedby the user. In this manner, the cover layer 1502 can be used as anavigation device by defining, for example, a “left edge press” with adifferent function from a “right edge press,” and so forth.

The cover layer 1502 can also be used as an output. In one or moreembodiments, the control circuit actuates the piezoelectric devices 1515in accordance with an audio signal to use the cover layer 1502 as anaudio transducer. Accordingly, the cover layer becomes a loudspeakerthrough which audio output can be delivered to a user. In someembodiments, the control circuit can actuate the piezoelectric devices1515 in accordance with pulse functions to deliver haptic feedback tothe user as well.

Turning now to FIG. 16, illustrated therein is a method, suitable for anelectronic device, for orienting images on a display in accordance withone or more embodiments of the invention. As shown at step 1601, adisplay 1663 of an electronic device 1661 is configured to providevisual output 1664 having a presentation orientation associatedtherewith. As step 1601 is the initial step in the method, thepresentation orientation of the visual output 1664 is the initialorientation.

At step 1602, user input is received by an interface element of theelectronic device 1661. The user input can take a variety of forms. Forinstance, in one embodiment the user input comprises audio input. Inanother embodiment, the user input comprises touch input along thedisplay 1663. In another embodiment, the user input comprises actuationof an input control device, such as a button, joystick, slider switch,rocker switch, or other device, that is operable with a control circuitdisposed within the electronic device 1661. In another embodiment, theuser input comprises a sensed gesture, such as movement of a body partto which the electronic device is connected, which may be sensed by anaccelerometer or gyroscope. In another embodiment, the user inputcomprises a light-sensed user action or an infrared-sensed user action,such as movement of the user's body, hands, or limbs away from theelectronic device 1661.

In response to the user input, the control circuit coupled to thedisplay can be configured to alter 1665 the presentation orientationfrom the initial orientation. As shown in illustrative step 1602, thealteration comprises a rotation of the presentation orientation in theclockwise direction. Note that it is not necessary to rotate or move thedisplay 1663 to change the presentation orientation. For instance, thedisplay 1663 can remain stationary in three-dimensional space while thepresentation orientation of the visual output 1664 rotates or otherwisechanges with reference to the physical orientation of the display 1663.Note also that the amount of alteration can depend upon theconfiguration of the electronic device 1661, the user input, or acombination of the two. For example, in one embodiment, the controlcircuit can be configured to alter 1665 the presentation orientation inan amount proportional to the user input. Where the user input comprisesa finger sweep across a surface of the electronic device 1661 or thedisplay 1663, the control circuit may alter 1665 the presentation in aproportional amount and in a corresponding direction. However, otheralteration schemes are possible as well. For instance, when a coverlayer of the display 1663 is configured as an input control device, thecontrol circuit may be configured to alter 1665 the presentationorientation by a predetermined rotation amount when the input controldevice is actuated. A press of the cover layer may result in, forexample, a 90-degree, 180, degree, or other amount of rotation.Predetermined rotation amounts can be associated with other user inputsas well, including gestures. Repeated presses of the cover layer mayresult in additional rotation of the predetermined amount, for example,one press of the cover layer resulting in a 90-degree rotation, with asecond press resulting in an additional 90-degree rotation for a totalof 180 degrees, and so forth.

In addition to rotation, the control circuit can be configured toperform other alterations in response to user input as well. The controlcircuit can be configured to alter one of a color, a resolution, ascaling, or a magnification of the visual output upon altering thepresentation orientation in response to the user input. Otheralterations will be obvious to those of ordinary skill in the art havingthe benefit of this disclosure.

At step 1603, a non-user event occurs. Non-user events are events thatoccur in the absence of user input to user interface devices. Non-userevents can take a variety of forms. Non-user events can be user definedas well. Examples of non-user events include incoming telephone calls,an incoming text message, an incoming multimedia message, a low batterywarning, expiration of a timer, or a calendar alarm event. Where theelectronic device 1661 includes wellness sensors, the non-user inputevent comprises a detected user wellness condition sensed by the userwellness sensors. Detected wellness events are non-user events becausethey do not result from manipulation of user interface devices, butrather from signals sensed from user monitoring devices, e.g., thewellness sensors (334) described above with reference to FIG. 3.

When the non-user event occurs, the control circuit is configured torevert 1666 the presentation orientation back to the initialorientation. This not only returns the presentation orientation to onethat is generally most readily accessible by the user, but also servesas a notification that the non-user event has occurred. The controlcircuit can optionally take additional steps as well, such as presentinga prompt 1667 on the display after reverting the presentationorientation to the initial orientation.

Turning now to FIGS. 17-18, the method described with reference to FIG.16 will be illustratively described. Starting at step 1701, a user 1770has a wearable electronic device 1761 strapped to his wrist. The display1763 of the wearable electronic device 1761 presents visual output 1764with a presentation orientation that is an initial orientation.

At step 1702, the user makes a gesture 1771, which in this illustrationis a sweeping motion of his hand 1772. A motion detector disposed in thewearable electronic device 1761, which may be an accelerometer orgyroscope, senses the motion caused by this gesture 1771 and delivers asignal corresponding thereto to a control circuit. Upon receiving theuser input, the control circuit alters the presentation orientation fromthe initial orientation to a second presentation orientation 1773. Inthis illustration, the second presentation orientation is apredetermined rotation amount of 180 degrees, thus causing the visualoutput 1764 to “flip” upside down on the display 1763.

At step 1801, an event occurring in absence of further user inputoccurs. In this illustration, the event is an incoming telephone call1880. Upon detecting this non-user event, the control circuit reverts1881 the presentation orientation of the visual output on the display tothe initial orientation. The initial orientation is shown in step 1802.Note that this has transpired without additional gestures by the user.However, in this illustrative embodiment, the same would be true ifthere had been gestures, because the control circuit is configured torevert the presentation orientation of the visual output on the displayto an initial orientation independent o fuser input when a non-userevent is detected.

Turning now to FIG. 19, illustrated therein is another method fororienting visual output 1964 on the display 1963 of an electronic device1961 in accordance with one or more embodiments of the invention. InFIG. 19, the visual output 1964 has associated therewith a user inputconfiguration. The user input configuration 1994 comprises actuationtargets or other user controls that, when actuated, provide user inputto the electronic device 1961. For instance, where the display 1963 is atouch sensitive display, the user input configuration 1994 forms a userinterface with which a user may control the operation and functionalityof the electronic device 1961. The user input configuration 1994 caninclude visual or non-visual user actuation targets present on thedisplay 1963 of the electronic device 1961. Alternatively, the userinput configuration can be a configuration of a morphing or otherwiseconfigurable keypad, e.g., smart keys, or user interaction devicedisposed along a surface of the electronic device 1961.

Illustrating by example, the telephone dialer shown in FIG. 12 wouldhave a user input configuration associated therewith because touchingany of the dialers in the telephone dialer would correspond to userentry of a telephone number to be dialed. In another example, presumethat the electronic device 1961 included three configurable buttons onits left side. In one mode of operation, actuation of the top buttonresults in the visual output 1964 scrolling up, while actuation of thebottom button results in the visual output 1964 scrolling down.Actuation of the center button causes a soft user actuation target onthe display 1963 highlighted in the visual output 1964 to be executed.The user input configuration 1994 associated with the visual output 1964would be the configuration of the configurable buttons.

At step 1901, a control circuit of the electronic device 1961 presentsthe visual output 1964 on the display 1963 in an initial orientation.The user input configuration 1994 is presented in an initial dispositionas well. The initial disposition of the user input configuration 1994 isoriented the same as the presentation orientation of the visual output1964.

At step 1902, user input is received. As described above, the controlcircuit alters 1965 the presentation orientation of the visual output1964 in response to the user input. The control circuit can then takeone of a variety of options with the user input configuration 1994depending upon the application running on the electronic device 1961,how the user has defined the control settings of the electronic device1961, user preferences, or other factors.

In a first embodiment, shown to the left of the electronic device 1961in step 1902, the control circuit is configured to alter 1967 theinitial disposition of the user input configuration 1994 in response tothe user input. In one embodiment, the control circuit is configured toalter 1967 the initial disposition of the user input configuration 1994proportionally with the alteration of the presentation orientation ofthe visual output 1964. However, the initial disposition of the userinput configuration 1994 could be altered in amounts different from thevisual output 1964 as well.

In a second embodiment, shown to the right of the electronic device 1961in step 1902, the control circuit is configured to retain the user inputconfiguration 1994 in the initial disposition when the presentationorientation is altered in response to the user input. This secondembodiment is advantageous when, for example, a user is showing picturesto a colleague on the display 1963. The user may wish to flip thepicture, i.e., flip the visual output 1964 over so that the colleaguecan see it. However, the user may wish to retain the user inputconfiguration 1994 so as not to have to scroll backwards. If thepresentation of pictures has associated therewith a user inputconfiguration 1994 that causes leftward scrolling when the left side ofthe display 1963 is pressed, and rightward scrolling when the right sideof the display 1963 is pressed, without the ability to retain the userinput configuration 1994 when altering the presentation orientation, theuser would have to press left to scroll right and vice versa. Theability to retain the initial disposition of the user inputconfiguration 1994 allows the user to retain the intuitive, properlyoriented scrolling control while simultaneously flipping a pictureassociated with that control around so as to be visible to a friend.

Turning to FIGS. 20-21, the method of FIG. 19 will be graphicallydescribed. Starting at step 2001, a user 2070 has a wearable electronicdevice 2061 strapped to his wrist. The display 2063 of the wearableelectronic device 2061 presents visual output 2064, which in this caseis a picture that the user 2070 wishes to show to a friend who is facinghim. The visual output 2064 is presented with presentation orientationthat is an initial orientation. In this example, the bottom of thepicture is towards the user 2070.

The visual output 2064 also has associated therewith a user interface2094. As the visual output 2064 is being presented in a photo-displayingapplication, the application is configured such that certain fingergestures cause certain actions to occur. For simplicity of discussion,presume that touching a left side of the display 2063 scrolls to aprevious picture, while touching a right side of the display 2063scrolls to a subsequent picture. As shown at step 2001, the initialdisposition of the user interface 2094 is oriented with the initialorientation of the visual output 2064.

At step 2002, the user 2070 delivers user input to the wearableelectronic device 2061. The user input in this example is a swirlingmotion made with a finger on the display 2063. This causes thepresentation orientation of the visual output to be altered 2065.However, to preserve a common navigation control scheme, the initialdisposition of the user interface 2094 is retained. Thus, the user canstill touch a left side of the display 2063 to scroll to a previouspicture, while touching a right side of the display 2063 will scroll toa subsequent picture.

At step 2101, a non-user event occurs. In this illustration, thenon-user event is an incoming telephone call 2180. Upon detecting thisnon-user event, the control circuit reverts 2081 the presentationorientation of the visual output on the display to the initialorientation. The initial orientation is shown in step 2102. Since theuser interface 2094 was retained in step 2002 above, it does not need tobe altered.

Turning now to FIGS. 22-23, illustrated therein is another use case thatcan occur using electronic devices configured in accordance withembodiments of the invention. At step 2201, a first user 2220 and asecond user 2221 are engaged in a conference call, with a detachableelectronic module 2200 in a folded configuration being used as thecommunication device. Initially, the first user 2220 is speaking.Accordingly, the visual output 2263 is oriented towards the first user2220. The detachable electronic module 2200 of this illustrationincludes a plurality of audio input devices, with one audio input device2222 being disposed such that its audio receive cone is directed towardsthe first user 2220. The second audio input device 2223 is disposed suchthat its audio receive cone is oriented towards the second user 2221.Similarly, the detachable electronic module 2200 also includes adirectable audio output comprising a first speaker 2224 directed to thefirst user 2220 and a second speaker 2225 directed towards the seconduser 2221.

While the first user 2220 is speaking, not only is the visual output2263 oriented toward the first user 2220, but so too are the audio inputand the audio output. In step 2201, the first user 2220 finishesspeaking and wishes to let the second user 2221 speak. Accordingly, thefirst user 2220 provides user input by gesturing with a hand 2226. Thisgesture is detected by an infrared sensor of the detachable electronicmodule 2200.

In response to detecting the user input, the control circuit isconfigured to alter 2227 the presentation orientation of the visualoutput 2263 so that the visual output 2263 is oriented towards thesecond user 2221. The control circuit of this example further isoperable to switch between audio input devices 2222,2223 upon alteringthe presentation orientation in response to the user input. In oneembodiment, the switching results in the first audio input device 2222being turned off and the second audio input device 2223 being turned on.Further, the control circuit is operable to redirect output audio uponaltering the presentation orientation in response to the user input.This can include increasing the volume of the second speaker 2225 whilereducing the volume of the first speaker 2224. The result of thesealterations is shown in step 2202.

At step 2301, the second user 2221 is finished talking and leaves theroom. With reference to the first user 2220, this constitutes a non-userevent because it occurs in the absence of user input from the first user2220. The infrared sensor of the detachable electronic module 2200detects the second user 2221 leaving. Accordingly, the control circuitreverts 2327 the presentation orientation of the visual output 2263 backto the first user 2220. Simultaneously, the control circuit of thisexample switches between audio input devices to direct the audio inputback to the first user 2220. Further, the control circuit redirectsoutput audio upon altering the presentation orientation back to thefirst user 2220. Since the second user 2221 is no longer in the vicinityof the detachable electronic module 2200, as detected by the infraredsensor, the second speaker 2225 can be turned off. The result of thesealterations is shown in step 2302.

The above discussion not withstanding, FIGS. 22 and 23 can be used toillustrate yet another use case that can occur using electronic devicesconfigured in accordance with embodiments of the invention. At step2201, a first user 2220 and a second user 2221 are engaged in theviewing of content on the detachable electronic module 2200 such aspictures. In this case the first user 2220 is showing the second user2221 the pictures but controlling the slideshow via voice recognition.Accordingly, the visual output 2263 is oriented towards the first user2220. The detachable electronic module 2200 of this illustrationincludes a plurality of audio input devices, with one audio input device2222 being disposed such that its audio receive cone is directed towardsthe first user 2220. The second audio input device 2223 is disposed suchthat its audio receive cone is oriented towards the second user 2221.

While the first user 2220 is manipulating the detachable electronicmodule 2200 to find the appropriate content to show the second user2221, not only is the visual output 2263 oriented toward the first user2220, but so too is the audio input. In step 2201, the first user 2220finds the content and wishes to show it to the second user 2221.Accordingly, the first user 2220 provides user input by gesturing with ahand 2226. This gesture is detected by an infrared sensor of thedetachable electronic module 2200.

In response to detecting the user input, the control circuit isconfigured to alter 2227 the presentation orientation of the visualoutput 2263 so that the visual output 2263 is oriented towards thesecond user 2221. The control circuit of this example remains audioinput device 2222 upon altering the presentation orientation in responseto the user input. The result of these alterations is shown in step2202. The result of these alterations allow the second user 2221 to viewthe images in the correct orientation, while allowing the first user2220 to control the manipulation of the images via voice commands usingthe audio input device 2222.

As in the earlier example the presentation orientation can revert backto the first user due to a non-user event such as the second user 2221leaving. Alternatively, the first user can manually revert thepresentation orientation back in his direction by the use of a gestureor voice command.

Turning now to FIGS. 24-25, illustrated therein is another method oforienting images on the display of an electronic device 2461 inaccordance with one or more embodiments of the invention. Recall fromthe discussion of FIGS. 19-21 that in one or more embodiments, thecontrol circuit of the electronic device 2461 can be configured to alterthe presentation orientation of the visual output 2464 in response touser input while retaining the user interface component 2494 in aninitial disposition. The user interface component 2494 is held while thepresentation orientation of the visual output 2464 is altered. One ofordinary skill in the art with the benefit of this disclosure willrecognize that the retention of the initial disposition of the userinterface component 2494 can be with respect to various referencepoints. For example, the initial disposition can be with reference tothe display 2463, the housing of the electronic device 2461, an edge ofthe display 2463, or other physical element of the electronic device2461. In such an embodiment, when the electronic device 2461 is moved inthree-dimensional space 2400, represented in FIG. 24 by three axes, theuser interface component 2494 will remain constantly aligned with, forinstance, an edge or corner of the display. This embodiment wasillustrated in FIG. 20, where the user interface (2094) was retained inan initial disposition fixed relative to the physical orientation of thedisplay (2063).

In another embodiment, the retention of the initial disposition of theuser interface component 2494 can be with reference to its initialbearing in three-dimensional space 2400. Said differently, where theinitial disposition of the user interface component 2494 is representedin three-dimensional space 2400 with a bearing along the x-axis 2450,the y-axis 2451, and the z-axis 2452 in three-dimensional space 2400,these bearings can be held while the visual output 2464 is altered. Itis this latter embodiment that is shown in FIGS. 24-25.

Starting at step 2401, a user 2470 has an electronic device 2461strapped to his wrist. The display 2463 of the electronic device 2461presents visual output 2464 with a presentation orientation that is aninitial orientation. The visual output 2464 is presented withpresentation orientation that is an initial orientation. In thisexample, the bottom of the visual output 2464 is towards the body of theuser 2470. The visual output 2464 also has associated therewith a userinterface component 2494. The user interface component 2494 couldcomprise a plurality of user actuation targets, a data entry surface,such as one that can be written on with a stylus or other device, aconfiguration of physical keys, soft keys, or combinations thereof, apreferred voice input direction, or other user input devices. As shownat step 2401, the initial disposition of the user interface component2494 is oriented with the initial orientation of the visual output 2464.

At step 2402, the user makes a gesture 2471, which in this illustrationis a sweeping motion of his hand 2472. A motion detector disposed in theelectronic device 2461, which may be an accelerometer, compass,gyroscope, or other device, senses the motion caused by this gesture2471 and delivers a signal corresponding thereto to a control circuit.Upon receiving the user input, the control circuit alters thepresentation orientation from the initial orientation to a secondpresentation orientation. In this illustration, the second presentationorientation is a predetermined rotation amount of 180 degrees, thuscausing the visual output 2464 to “flip” upside down on the display2463.

To preserve a common navigation control scheme, the initial dispositionof the user interface component 2494 is retained. In this illustrativeembodiment, the user interface component 2494 is retained in an initialdisposition with a bearing fixed relative to the initial disposition'sorientation in three-dimensional space 2400. Thus, despite the fact thatthe user's arm has rotated by 90 degrees, the user 2470 still has theuser interface component 2494 facing him. Thus, if writing letters onthe display 2463 with a stylus, the user could write them “right-sideup” rather than having to write them in an odd orientation.

At step 2501, the user 2470 makes another gesture 2571 in the oppositedirection. Upon detecting this gesture 2571, the control circuit reverts2581 the presentation orientation of the visual output 2464 on thedisplay 2463 to the initial orientation. The initial orientation isshown in step 2502. However, the initial disposition of the userinterface component 2494 is retained with a bearing in three-dimensionalspace 2400 as shown in both steps 2501,2502.

Turning now to FIGS. 26-27, illustrated therein is a method for alteringa portion 2655 of the user interface component 2694 when altering thepresentation orientation of visual output 2664 on the display 2663 of anelectronic device 2661 in accordance with one or more embodiments of theinvention. To this point, when user interface elements have been alteredor retained, the examples have shown the entire user interface beingaltered or retained as a unit. However, it will be apparent to those ofordinary skill in the art having the benefit of this disclosure thatportions of the user interface can be altered while other portions areretained. As noted in the discussion above, the retained portions can beretained in an orientation fixed relative to the electronic device 2661or bearings fixed in three-dimensional space (2400). In the illustrativeembodiment of FIGS. 26-27, a portion 2655 of the user interfacecomponent 2694 will be altered proportionally with the visual output2664, while other portions are retained in an initial disposition fixedrelative to both the electronic device 2661 and three-dimensional spacedue to the fact that the orientation of the electronic device 2661remains unchanged.

Starting at step 2601, a user 2670 has a wearable electronic device 2661strapped to his wrist. The display 2663 of the wearable electronicdevice 2661 presents visual output 2664, which in this case is a picturethat the user 2670 wishes to show to a friend. The visual output 2664 ispresented with presentation orientation that is an initial orientation.In this example, the bottom of the picture is towards the body of theuser 2670.

The visual output 2664 also has associated therewith a user interfacecomponent 2694. As shown at step 2601, the initial disposition of theuser interface component 2694 is oriented with the initial orientationof the visual output 2664.

At step 2602, the user 2670 delivers user input to the wearableelectronic device 2661 by pressing a physical key disposed on thewearable electronic device 2661. In this illustrative embodiment,actuation of the physical key causes the control circuit to alter thepresentation orientation by a predetermined rotation amount, which is 90degrees in this example. A portion 2655 of the user interface component2694 is altered proportionally with the presentation orientation of thevisual output 2664. Another portion of the user interface component 2694is retained in its initial disposition. The same happens again at step2701, when the user actuates the physical key again, thus rotating boththe portion 2655 of the user interface component 2694 and thepresentation orientation by another 90 degrees, while retaining theremainder of the user interface component 2694 in its initialdisposition.

At step 2702, a non-user event occurs. In this illustration, thenon-user event is an incoming telephone call 2780. Upon detecting thisnon-user event, the control circuit reverts the presentation orientationof the visual output 2664 and the portion 2655 of the user interfacecomponent 2694 to the initial orientation.

With regards to this explanatory embodiment, portions of the userinterface that remain in their initial disposition and portions that arereoriented can be different modes of a user interface. For example, apreferred voice input direction can remain in its initial disposition,while touch navigation inputs are reoriented with the presentationorientation. Alternatively gesture input can remain in its initialdisposition while touch navigation input is reoriented with thepresentation orientation.

Turning now to FIG. 28, illustrated therein is another use casedemonstrating how wellness sensors disposed within an electronic devicecan be used not only to revert the presentation orientation, audioinput, audio output, or combinations thereof, but also to perform otherfeatures as well.

As shown in FIG. 28, a store patron 2820 has passed out due to thestress of seeing a robbery in place. A robber 2821 is holding a clerk2822 at gunpoint. The stress of this event has simply caused the storepatron 2820 to faint. However, the store patron 2820 is fortunate enoughto be wearing a wearable electronic device 2800 configured in accordancewith one embodiment of the invention. This wearable electronic device2800 is equipped with wellness sensors. The wellness sensors have sensedvery abnormal vital signals from the store patron 2820. For example, hisheart rate may have spiked through the roof only to fall upon fainting.Further, his temperature may have experienced variations as well.Perspiration may be present. More importantly, the wellness sensors arecapable of detecting that the store patron 2820 has fallen and is nowmotionless after exhibiting the abnormal vital signs.

In the scenario of FIG. 28, the store patron 2820 cannot speak due tohaving fainted. However, the wearable electronic device 2800 isconfigured to transmit emergency alerts upon detecting that the storepatron 2820 has experienced unusual physical conditions, has fallen, andis motionless. The wearable electronic device 2800 pulls locationinformation from the global positioning sensor. The electronic devicethen sends an emergency communication message 2823 to the appropriateemergency services personnel through an emergency services call number,such as 911 or SOS. The emergency services call number will depend uponwhat regional authorities use as an appropriate emergency services callnumber. The emergency communication message 2823 is then sent to theemergency services center 2824. This transmission can be through any ofa variety of methods, including short message services, multimediamessage services, instant messaging, messaging over session interruptprotocol, and so forth. Emergency personnel 2825 can then be dispatchedto render assistance.

Turning now to FIG. 29, illustrated therein is a method 2900 oforienting images in accordance with embodiments of the invention shownin flow-chart form. Most of the steps of FIG. 29 have been described indetail above, and as such, will be mentioned only briefly here.

At step 2901, the method 2900 receives user input. As noted above, theuser input can comprise one of audio input, touch input on the display,actuation of an input control device operable with the control circuit,a sensed gesture, a light-sensed user action, an ultrasonic-sensed useraction, or an infrared-sensed user action. Other examples of user inputwill be obvious to those of ordinary skill in the art having the benefitof this disclosure.

At step 2902, a presentation module operable with a display isconfigured to alter a presentation orientation of visual output from aninitial orientation in response to receiving user input. This alterationcan include rotating the visual output. Optionally, the alteration caninclude altering one of a color, a resolution, a scaling, or amagnification of the visual output, or combinations thereof. At step2903, the presentation module can optionally maintain an initialdisposition of a user input configuration associated with the visualoutput on a user interface.

At decision 2904, device events or non-user events are detected.Examples of these include an incoming telephone call, an incoming textmessage, an incoming multimedia message, a low battery warning, or acalendar alarm event. Device events can also include wellness factors ofthe user sensed by wellness detectors. When a device event or a non-userevent occurs, the presentation module can revert the presentationorientation of the visual output on the display to an initialorientation at step 2905. Until the device event or non-user eventoccurs, the presentation module can retain the user-defined orientationat 2906 until additional user input requiring redirection of the visualoutput is received.

Turning now to FIG. 30, illustrated therein is a detachable electronicmodule 3001 having a control circuit 3003 disposed within a centralhousing 3002 of the detachable electronic module 3001. The centralhousing 3002 is the portion of the detachable electronic module 3001that is disposed between the first electronic module extension 3007 andthe second electronic module extension 3008, which are hingedly coupledto a first side 3004 and a second side 3005 of the central housing 3002.The first electronic module extension 3007 and the second electronicmodule extension 3008 extending distally from the opposite first side3004 and second side 3005 of the central housing 3002, and areconfigured to be selectively pivotable about the central housing 3002.

As shown in FIG. 30, each electronic module extension 3007,3008 includesonly a power source 3113 (and corresponding safety and/or chargingcomponents) and an electronic coupling structure 3114 through whichenergy can be delivered to and from the power source 3113. In oneembodiment, the electronic coupling structure 3114 is integrated withthe hinges 3010,3011, For example, the hinges 3010,3011 can compriseelectrical contacts configured to couple to an external power source tothe power sources 3113 disposed within the electronic module extensions3007,3008.

In one embodiment, the power source 3113 comprises a rechargeablebattery. All other electronics associated with the operating modes ofthe detachable electronic module 3001, e.g., the control circuit 3003and memory 3115, are disposed within the central housing 3002. The powersource 3113 is thus configured to deliver energy to electroniccomponents disposed only within the central housing 3002.

The hinges 3010,3011 can include a variety of features. For example, inone embodiment the hinges 3010,3011 are pre-loaded with a biasingelement 3116 such as a spring. Pre-loading with a biased hinge can beused, for example, to retain the first electronic module extension 3007and the second electronic module extension 3008 in one of the angularlydisplaced open position or the closed position.

In another embodiment, the hinges 3010, 3011 are detented with detentingelements 3117. For example, a detented hinge having a plurality ofdetent stops can be configured to hold one or both of the firstelectronic module extension 3007 or the second electronic moduleextension 3008 in one of a plurality of angularly displaced alignmentsrelative to the central housing 3002.

The control circuit 3003 in this embodiment is operable to alter anoperating mode of the detachable electronic module 3001 to one of aplurality of functional modes depending upon the angularly displacedorientation of the electronic module extensions 3007,3008 relative tothe central housing 3002. The operable modes can be any of thefollowing: a desktop mode, a telephone mode, a wristwatch mode, healthmonitoring mode, a clock mode, a calendar mode, a gaming mode, aOn-Star™ physical safety mode, an ON mode, an OFF mode, a securitydevice mode, a baby monitor mode, a headset type mode, a scale functionmode, or a media player mode. An example of a desktop mode may includefeatures found in a desktop, palmtop, or tablet computer, such as aspeaker phone, web browser, gaming applications, WiFi communicationcapabilities, and so forth. A telephone mode may include wide areanetwork communication capabilities such that the detachable electronicmodule 3001 can function as a cellular phone. A wristwatch mode mayinclude displaying the time, date, and calendar events. A clock mode maysimply present the time on the display. A calendar mode may simplypresent calendar events on the display. A gaming mode may present gamingindicia and/or controls on the display. A media player mode may playmusic or videos on the display. A On-Star™ mode may monitor suddengravitational force changes, such as a person falling. A security devicemode may trigger audio monitoring and alerts. A scale mode my enablescale function when device is placed stationary flat on a tabletop.These modes are explanatory only, as others will be obvious to those ofordinary skill in the art having the benefit of this disclosure.

An extension detection sensor 3009 is configured to detect an angularlydisplaced location of one or both of the first electronic moduleextension 3007 or the second electronic module extension 3008. Forexample, in one embodiment the hinges 3010,3011 are equipped withelectrical sensors capable of determining a rotational amount of eachhinge 3010,3011. The extension detection sensor 3009 can then correlatethe amount of rotation with an estimated angularly displacedorientation. In an alternate embodiment, where the hinges 3010,3011 aredetented, the extension sensor can detect with electrical switching inwhich détente a electronic module extension stop is resting, and thusdetermine the angularly displaced orientation.

Once the angularly displaced orientation of one or both of the firstelectronic module extension 3007 or the second electronic moduleextension 3008 is known, a mode selector 3112, operable with the controlcircuit 3003, can select one of the plurality of functional modes basedupon the angular position detected by the extension detection sensor3009. This will be illustrated in subsequent use cases.

The mode selector 3112 and extension detection sensor 3009 can beconfigured as executable instructions stored in the memory 3115. A flowchart of an illustrative method suitable for altering the operatingmodes of the detachable electronic module 3001 is shown in FIG. 31.

Turning now to FIG. 31, the method 3100 begins at step 3100 where theextension detection sensor (3009) detects an angular position of one ormore electronic module extensions (3007,3008) that pivotally coupled toa central housing (3002) and configured for selective movement between aplurality of angular displaced positions relative to the central housing(3002). At step 3102, the control circuit (3003) or extension detectionsensor (3009) can correlate a detected angular position with afunctional mode of the detachable electronic module (3001). At step3103, the control circuit (3003) can transition the operational mode ofthe detachable electronic module (3001) to a correlated functional modein response to the detecting the angular position of the electronicmodule extensions (3007,3008).

The extension detection sensor (3009) can continue to monitor theangular positions of the electronic module extensions (3007,3008). Wherethere is a change, detected at decision 3104, the method 3100 canrepeat, resulting in the control circuit (3003) again transitioning theoperational mode of the detachable electronic module (3001) to anothercorrelated functional mode in response to the detecting the angularposition of the electronic module extensions (3007,3008). Turning now toFIGS. 32-44, illustrated therein will be several use cases demonstratinghow the operational mode of various detachable electronic modules can bealtered by changing the angularly displaced orientations of theelectronic module extensions relative to the central housing.

Beginning with FIGS. 32-33, illustrated therein is a detachableelectronic module 3200 having substantially planar electronic moduleextensions 3307,3308. In FIGS. 32-33, the electronic module extensions3307,3308 have been rotated to a closed position. In the closedposition, the electronic module extensions 3307,3308 are disposedagainst a major face 3301 disposed on the rear side of the centralhousing 3302.

As previously described, the control circuit disposed within the centralhousing 3302 can be configured to alter the operating mode of thedetachable electronic module 3200 to one of a plurality of functionalmodes as a function of the position of the electronic module extensions3307,3308. In the embodiment of FIGS. 32-33, the electronic moduleextensions 3307,3308 are substantially planar. By pivoting theelectronic module extensions 3307,3308 to the closed position, a usermay want to place the detachable electronic module 3300 in a desktopmode, speakerphone mode, or gaming mode. In one embodiment, the controlcircuit is user programmable to function in a predefined, user-selectedmode when the electronic module extensions 3307,3308 are in the closedposition.

FIGS. 34-35 illustrate a similar detachable electronic module 3400having electronic module extensions 3507,3508 in the closed position aswell. In FIGS. 34-35, the electronic module extensions 3507,3508 arenon-planar and have a curved cross section. Accordingly, when theelectronic module extensions 3507,3508 are in the closed position, onlya portion 3509,3510 of the electronic module extensions 3507,3508touches the rear face 3511 of the housing 3502. One advantage ofnon-planar electronic module extensions 3507,3508 is that objects can bedisposed within the voids between the electronic module extensions3507,3508 and the rear face 3511. For example, in the closed positionshown in FIGS. 34-35, the electronic module extensions 3507,3508 can beused as “clips” to hold the detachable electronic module 3400 onto apurse strap, a backpack strap, and so forth.

In the illustrative embodiment of FIGS. 34-35, since the control circuitis configured to select the one of the plurality of functional modesbased upon the angular position of the electronic module extensions3507,3508. Thus, the detachable electronic module 3400 of FIGS. 34-35 isoperating in a first operating mode.

By contrast, in FIG. 36, the electronic module extensions 3507,3508 havebeen pivoted about the central housing 3502 to an angularly displacedopen position extending distally outward from the housing 3502.Accordingly, the control circuit changes the operational mode to anothermode that is different from that occurring in FIGS. 34-35. Illustratingby example, the operational mode in FIGS. 34-35 may have been a clockmode, while the operational mode in FIG. 36 is a health monitoring mode,and so forth.

Turning to FIGS. 37-43, illustrated therein is another detachableelectronic module 3700 configured in accordance with one or moreembodiments of the invention. In FIGS. 37-43, three differentoperational modes are shown. Each operational mode is a function of theradial alignment of the electronic module extensions 3807,3808 relativeto the central housing 3702 of the detachable electronic module 3700.Each operating mode is selected from a plurality of predeterminedoperating modes of which the detachable electronic module 370 is capableof executing. A first mode is shown in FIGS. 37-38, while a second isshown in FIGS. 39-40. A third mode is shown in FIG. 41, while a fourthmode is shown in FIGS. 42-43. FIGS. 42-43 also depict how externalelectrical contacts 4201 can be hidden and revealed, or protected andexposed, as a function of the angularly displaced orientation of theelectronic module extensions 3807,3808.

In FIGS. 37-38, the electronic module extensions 3807,3808 are in theclosed position, with each electronic module extensions 3807,3808 beingfolded completely about its respective hinge device 3703,3704 to adisplaced location against the back of the central housing 3702. Thecontrol circuit disposed within the central housing 3702 detects thisand configures the detachable electronic module 3700 to operate in afirst operational mode. The first operational mode may comprise amultimedia player mode where a video is presented on the display.

By contrast, in FIGS. 39-40, each electronic module extension 3807,3808is placed in a partially open angular displacement relative to thecentral housing 3702. Accordingly, the control circuit disposed withinthe central housing 3702 detects this and configures the detachableelectronic module 3700 to operate in a second operational mode. Thesecond operational mode may comprise a clock mode where the time of dayis presented on the display to simulate a desk clock appearance.

FIG. 41 illustrates the electronic module extensions 3807,3808 being inthe open position. Accordingly, the control circuit disposed within thecentral housing 3702 detects this and configures the detachableelectronic module 3700 to operate in a third operational mode. The thirdoperational mode may comprise a health monitoring mode because theelectronic module extensions 3807,3808 are open and can be coupled to astrap for wearing on a wrist. When a strap that is selectivelydetachable from the detachable electronic module 3700 is attached, inone embodiment the control circuit actuates the health monitoring mode.In one embodiment, the control circuit is configured to convert theoperating mode to modes other than the health monitoring mode when oneor both of the first electronic module extension 3807 and the secondelectronic module extension 3808 is in the closed position, as shown inFIGS. 37-38.

FIGS. 42-43 illustrate a first electronic module extension 3807 being inthe open position, while the second electronic module extension 3808 isin the closed position. Accordingly, the control circuit disposed withinthe central housing 3702 detects this and configures the detachableelectronic module 3700 to operate in a fourth operational mode. Thefourth operational mode may comprise a clock mode where the time of dayis presented on the display to simulate a desk clock appearance.

The electronic module extensions 3807,3808 of FIGS. 37-42 are configuredwith a different form factor as well. The form factor of FIGS. 37-42includes both aesthetic elements and functional benefits. As shown inFIG. 38, the electronic module extensions 3807,3808 are configured withasymmetric geometries such that they nest when placed in the closedposition. This asymmetric contour having two side elements 3801,3802 anda non-orthogonal, inclined third surface 3803 offer a unique aestheticappearance.

At the same time, the electronic module extensions 3807,3808 also havefunctional elements that are different from previously disclosedembodiments. For example, each electronic module extension 3807,3808 hasan aperture 3804,3805 that can be used for attaching the detachableelectronic module 3700 to various devices, including shirts, jackets,purses, backpacks, and the like.

FIGS. 42-43 illustrate another feature that the foldable electronicmodule extensions 3807,3808 offer. As shown in FIG. 42, the bottom sideof the electronic module extensions 3807,3808 includes an externallyexposed electrical contact 4201. While in on embodiment externalcharging contacts are disposed at the hinge devices 3703,3704, in someapplications it can be advantageous to place the charging contacts onmajor faces of the electronic module extensions 3807,3808. Such anembodiment is shown in FIG. 42.

Where there is one or more externally exposed electrical contact 4201 ona major face of the electronic module extensions 3807,3808, closing theelectronic module extensions 3807,3808 covers and protects theexternally exposed electrical contact 4201. Said differently, theexternally exposed electrical contact 4201 his hidden when the one orboth of the first electronic module extension 3807 or the secondelectronic module extension 3808 is in the closed position, but isrevealed when the electronic module extensions 3807,3808 are in the openposition.

FIG. 44 shows an alternate detachable electronic module 4400 havingexternally exposed electrical contacts 4401,4402 disposed on theelectronic module extensions 4407,4408. In the embodiment of FIG. 4, theexternally exposed electrical contacts 4401,4402 are disposed on outermajor faces of the electronic module extensions 4407,4408. Accordingly,when the electronic module extensions 4407,4408 are in the closedposition, the externally exposed electrical contacts 4401,4402 areconcealed from view with reference to a viewer looking at the front ofthe detachable electronic module 4400. At the same time, the externallyexposed electrical contacts 4401,4402 are still exposed. Thisconfiguration allows the externally exposed electrical contacts4401,4402 to be rotated out of sight, while still being accessible.Accordingly, the detachable electronic module 4400 can be coupled to anexternal power source, e.g., placed in a charger or other device, whilethe electronic module extensions 4407,4408 are in the closed position.

FIG. 45 illustrates additional mechanical features that can beincorporated into a detachable electronic module 4500 configured inaccordance with one or more embodiments of the invention. As mentionedabove, in one embodiment the first electronic module extension 4507 andthe second electronic module extension 4508 are coupled to the housingwith a biased hinge 4501 configured to bias the first electronic moduleextension 4507 and/or the second electronic module extension 4508towards one of the angularly displaced open position or the closedposition. Such a biased hinge 4501 is shown in FIG. 45. Specifically,the biased hinge 4501 has a spring, which serves as a tensioning elementthat is configured to bias the first electronic module extension 4507and/or the second electronic module extension 4508 towards one of theangularly displaced open position or the closed position.

As also described above, in one embodiment one or both of the firstelectronic module extension 4507 or the second electronic moduleextension 4508 is coupled to the housing by a detented hinge 4502comprising a plurality of detent stops 4503,4504 configured to hold theone or both of the first electronic module extension 4507 or the secondelectronic module extension 4508 in one of a plurality of angularlydisplaced alignments relative to the housing 4505. The detented hinge4502 is illustrated in FIG. 45.

In one or more embodiments, the detachable electronic module 4500includes retention devices 4510,4511,4512,4513 configured to retain oneor both of the first electronic module extension 4507 or the secondelectronic module extension 4508 in the closed position. The retentiondevices 4510,4511,4512,4513 can be disposed in one or more of thehousing 4505, the first electronic module extension 4507, or the secondelectronic module extension 4508. In the illustrative embodiment of FIG.45, the retention devices 4510,4511,4512,4513 comprise magnets, and aredisposed in the electronic module extensions 4507,4508 and the housing4505. Other suitable retention devices suitable for use with embodimentsof the invention include snaps, shaped detents, spring latches, and soforth.

As discussed above, the detachable electronic module 4500, in oneembodiment, can be selectively coupled to a strap. The strap can beactive or passive. It is contemplated that a user will want to attach ordetach the detachable electronic module 4500 from the strap while thestrap is on the wrist, which means that the attachment or detachmentwill occur with only one hand. To accomplish this, as shown in FIG. 46,in one embodiment the electronic module extensions 4507,4508 areconfigured to “hyperextend” 4601 to facilitate detachment from a strap.Hyperextension is the angular displacement of the electronic moduleextensions 4507,4508 past the open position, as shown in FIG. 46. In oneembodiment, the detachable electronic module 4500 configured forhyperextension is equipped with biased hinges such that thehyperextension is opposed by a tensioning device. Accordingly, in oneembodiment, when hyperextended, the tensioning device will cause theelectronic module extensions 4507,4508 to move back towards either theopen position or the closed position with a closing force 4602.

Turning to FIG. 47, illustrated therein is yet another detachableelectronic module 4700 having electronic module extensions 4707,4708configured in accordance with embodiments of the invention. In FIG. 47,each electronic module extension 4707,4708 has an electronic moduleextension battery door 4770,4771. A user may open each electronic moduleextension battery door 4770,4771 to selectively replace the batteries4772,4773 as needed. In one embodiment, the batteries 4772,4773 arerechargeable batteries. Accordingly, a user can remove the batteries4772,4773, couple them to a charger, and charge them for subsequent use.(As noted above, in other embodiments, the user may couple the entiredetachable electronic module to a charger without the need of removingany battery.) In another embodiment, the batteries 4772,4773 are primarybatteries configured for single use. As shown in FIG. 47, each battery4772,4773 of this embodiment has a geometric shape that is complementaryto the geometric shapes of the electronic module extension 4707,4708.

The electronic module extension battery doors 4770,4771, where included,offer a couple of advantageous features to a user. First and foremost, auser may simply replace the batteries 4772,4773 rather than having tocouple the entire detachable electronic module 4700 to a charger.Accordingly, a user can swap batteries 4772,4773 and continue using thedevice, rather than having to discontinue use and wait for apredetermined charging time to recharge the batteries.

As second advantageous feature is shown in FIG. 48. FIG. 48 illustratesfour operational modes of the detachable electronic module 4700 of FIG.47. In view 4801, each electronic module extension 4707,4708 has abattery (4773,4773) disposed therein. Accordingly, the detachableelectronic module 4700 is powered ON.

In one or more embodiments, the detachable electronic module 4700 can bepowered by a single battery. Thus, a user can “hot swap” one of thebatteries without powering down the device. For example, in view 4802,one of the batteries 4773 has been removed from its correspondingelectronic module extension 4708. The detachable electronic module 4700is still powered ON because the other battery (4772) is still disposedwithin its corresponding electronic module extension 4707, and ispowering the detachable electronic module 4700.

Similarly, in view 4803, the other battery 4772 has been removed fromits corresponding electronic module extension 4707. The detachableelectronic module 4700 is still powered ON because the other battery(4773) is still disposed within its corresponding electronic moduleextension 4708, and is powering the detachable electronic module 4700.Only when both batteries 4772,4773 are removed, as shown in view 4804,is the detachable electronic module 4700 powered OFF. The ability tohot-swap batteries is especially advantageous in operational modes suchas the health monitoring mode, because a user can selectively replaceeach battery without powering the device down, and thus without stoppingthe health monitoring features of the detachable electronic module 4700.

While battery doors are one option for providing a user-replaceablebattery feature, in another embodiment, the electronic module extensionshave self-contained batteries. Rather than opening a battery door toreplace a battery, the user simply detaches one or both electronicmodule extensions. Such an embodiment is shown in FIG. 49. As with thebattery doors, detachable electronic module extensions allow batteriesto be hot swapped without powering down the detachable electronicmodule.

FIG. 49 illustrates four operational modes of the detachable electronicmodule 4900 having detachable electronic module extensions 4907,4908. Inview 4901, each detachable electronic module extension 4907,4908 has abattery disposed therein. Each detachable electronic module extension4907,4908 is coupled to the detachable electronic module 4900.Accordingly, the detachable electronic module 4900 is powered ON.

As was the case in FIG. 48, in the explanatory embodiment of FIG. 49, asingle battery can power the detachable electronic module 4900. Thus, auser can hot swap one of the batteries by detaching the correspondingelectronic module extension without powering down the detachableelectronic module 4900. For example, in view 4902, one of the detachableelectronic module extensions 4908 has been removed from the detachableelectronic module 4900. The detachable electronic module 4900 is stillpowered ON because the other detachable electronic module extension 4907and its corresponding battery are still attached and powering thedetachable electronic module 4900.

Similarly, in view 4903, the other detachable electronic moduleextension 4907 has been removed from the detachable electronic module4900. However, the detachable electronic module 4900 is still powered ONbecause the other detachable electronic module extension 4908, with itscorresponding integrated battery, is still attached to the detachableelectronic module 4900 and is still powering the detachable electronicmodule 4900. Only when both detachable electronic module extensions4907,4908 are removed, as shown in view 4904, is the detachableelectronic module 4900 powered OFF.
